Omega-3 May Safely Treat Precancerous Bowel Polyps
March 18, 2010
The nutrient could help those at genetic risk for the growths, study finds. Treatment with a specific type of omega-3 fatty acid can shrink the number and size of precancerous polyps in people at high genetic risk of developing bowel cancer, British researchers say.
The study authors reported that the new treatment appears to work as well as a drug called celecoxib (Celebrex), which is prescribed for patients with bowel polyps linked to their genetic risk, but it doesn't cause heart-related side effects.
The study, published online March 18 in the journal Gut, examined 55 patients with a high genetic risk of developing precancerous polyps in the bowel.

Health Tip
Check Your Skin for Signs of Cancer
March 18, 2010
Suggestions for performing a self-exam Regular self-exams of the skin can help you spot the beginning signs of skin cancer, allowing you to start treatment while the cancer is in its early stage.
The American Academy of Dermatology says you should look for any changes in your skin, particularly a growth that changes in size or appearance. You should also look for any mole, birthmark or spot that appears irregular, changes color or size, or hurts or bleeds.

Newer Genetic Info Adds Little to Predicting Breast Cancer
March 17, 2010
Data on lesser known variants didn't improve powers of standard risk model Plugging certain genetic data into the standard risk-assessment model for breast cancer won't do much to help gauge a woman's odds for getting the disease, a new study shows.
Assessing a woman's breast cancer risk remains a work in progress for doctors. For years, experts have relied on what's known as the "Gail model," which asks women seven questions related to family history, medical history and other areas, and then predicts her risk for breast cancer.

Abusive Men Often Rationalize Their Behavior
March 17, 2010
Many think domestic violence is much more common than it is, researchers say. Men who physically abuse their partners overestimate how often such violence occurs, which helps them justify their own actions, according to a new study.
University of Washington researchers looked at 124 men enrolled in a larger study of treatment intervention for domestic violence. The men, who had committed violence against a partner in the previous 90 days, were asked to estimate the percentage of men who had ever engaged in seven forms of abuse: throwing something at a partner that could cause injury; pushing, grabbing or shoving a partner; slapping or hitting; choking; beating up a partner; threatening a partner with a gun; or forcing a partner to have sex against their will.

Sexual Desire, Satisfaction Don't Diminish During Pregnancy
March 17, 2010
Study found first, second trimesters don't mean lowered interest for most women. Although women have less sex as their pregnancy progresses, they don't enjoy the experience any less, new research shows.
"We've studied men's sexual health for many years, and we have not studied women's sexual health, concerns, issues and problems in the past, and there's a gender information gap," said Dr. Irwin Goldstein, editor-in-chief of The Journal of Sexual Medicine, in which this new study was recently published.

Cancer Articles Tend to Focus on Positive Outcomes
March 16, 2010
Newspaper, magazine stories shy away from negative side effects, end-of-life care, review finds. People often complain that media reports slant towards bad news, but when it comes to cancer most newspaper and magazine stories may be overly optimistic, U.S. researchers suggest.
Radiation May Help Those With Inoperable Lung Tumors
March 16, 2010
3-year survival doubled after the treatment, study found. A carefully targeted and powerful regimen of radiation therapy kept early-stage lung tumors stable in patients who had inoperable cancers.
Almost 56 percent of patients who underwent the therapy, called stereotactic body radiation therapy (SBRT), were still alive three years after their treatment, according to preliminary findings from a study published in the March 17 issue of the Journal of the American Medical Association, a themed issue on cancer.
By contrast, only about 25 percent to 30 percent of patients who receive conventional fractionated radiotherapy survive that long.

Older Colon Cancer Patients Less Likely to Get Chemo
March 16, 2010
Study found one in two went without, while 87% of younger patients got it after surgery. Older colon cancer patients are less likely than younger ones to receive potentially life-prolonging chemotherapy following surgery for their illness, a new study reveals.
The research indicates that those with advanced colon cancer who are over the age of 75 are both less likely to receive chemotherapy and more likely to receive less chemotherapy even when they are given the treatment.
Yet, prior research has indicated that surgery coupled with postoperative chemotherapy appears to reduce the risk of dying from the disease or experiencing a recurrence.

Prostate Cancer Radiation Side Effects May Subside With Time
March 16, 2010
Ten years later, many men weren't bothered by treatment's effects, study finds. The balance between using enough radiation to shield patients from prostate cancer's return while keeping side effects at bay may not be as tricky as once thought, new research shows.
That's because radiation-linked side effects appear to lessen with time. In fact, 10 years after treatment, prostate cancer patients didnt' report suffering more severe side effects after doctors boosted their radiation to levels that made tumor recurrence 50 percent less likely, researchers say.

Pain Relief Often Delayed for Cancer Patients
March 16, 2010
Referrals to palliative care programs come too late, survey finds. Palliative care services, which help people who are seriously ill relieve symptoms such as pain, are now found at most U.S. cancer centers, but many programs don't interact with patients until it's too late, study findings show.
Are New Chemo Treatments Cost-Effective?
March 16, 2010
Drug advances extend lives, but one study puts cost per life-year gained at about $66,200. New chemotherapy agents for metastatic colon cancer improve patient survival but are costly, says a new study.
Researchers at Emory University in Atlanta analyzed data from 4,665 patients, aged 66 and older, diagnosed with metastatic colon cancer between 1995 and 2005. Compared to those who received older chemotherapy agents, patients who received one or more of the six chemotherapy agents approved in the United States between 1996 and 2004 lived an average of 6.

Treat Women With Heart Attack Just Like Men
Study
March 16, 2010
That will increase their odds of survival, experts say. Women who suffer a heart attack are more likely to survive if they receive the same invasive treatments as men do, a new study suggests.
French researchers looked at more than 3,000 patients admitted to the hospital for heart attack and found that women were 57 percent less likely than men to undergo angiography, a procedure that identifies blocked arteries. Among patients with an especially serious form of heart attack called ST-elevation myocardial infarction, men were 72 percent more likely to receive clot-busting drugs and 24 percent more likely to undergo angioplasty, a procedure to reopen a blocked artery.

DNA Test May Cut Hospitalizations Caused by Blood Thinner
March 16, 2010
Determining sensitivity can prevent bleeding, clotting problems, study shows. A simple genetic test that helps doctors determine the best dose of the blood-thinner drug warfarin for individual patients could reduce hospitalizations by one-third during the early dose-adjustment phase, a new study has found.
The test identifies variations in two genes that strongly influence sensitivity to warfarin (Coumadin), which is used to prevent blood clots in people with high-risk conditions, such as atrial fibrillation, or after surgery to replace a heart valve.
"Genetic testing is a tool clinicians can use to more accurately predict the best warfarin dose early on," Dr.

MRIs shouldn't take the place of a good clinical exam, study finds. They had no symptoms, but 70 percent of able-bodied professional and collegiate hockey players in a U.S. study had abnormal hip and pelvis MRIs.
MRIs May Detect Hidden Tumors in Breast Cancer Patients
March 12, 2010
Older women with cancer in one breast should have the other breast scanned, researchers say. MRI scans are more likely to turn up undiagnosed tumors in the breasts of postmenopausal women who already had cancer in their other breast, researchers report.
However, the scans are less likely to detect tumors in premenopausal women, they added.
"Our findings are not really surprising because we know that the risk of breast cancer increases as age increases," lead investigator Dr.

Daylight Savings
Not a Bright Time for All
March 14, 2010
People with SAD may be more affected by the shift in daylight, experts say Most people will welcome the start of daylight savings time this Sunday because it starts to stay light longer, even if that means the early mornings will be dark once again.
However, that shift may not be such a welcome change for people with seasonal affective disorder (SAD), a seasonal depression that occurs in the fall and winter and is caused, at least in part, by the lack of daylight during these seasons. Some experts suspect that light in the morning may be especially important for helping people with SAD, as well as for jumpstarting circadian rhythms in all people.

Adding Garlic Might Cut Cancer Risk
March 12, 2010
New test finds those who eat the most have lower levels of a disease-causing process. A new type of urine test shows that eating plenty of garlic may lower levels of a cancer-causing process within the body.
This process, called nitrosation, converts some substances found in foods or contaminated water into cancer-causing compounds. Nitrosation is most commonly caused by nitrates from certain processed meats or high-heat food preparation methods, or by water contaminated by industrial or agricultural runoff.

Seaweed May Help Treat Lymphoma
March 11, 2010
Lab study finds extract slows cancer growth without affecting healthy cells. Seaweed extract has the potential to become a treatment for the immune system cancer known as lymphoma, according to the results of preliminary research.
In the study, researchers experimented with compounds derived from seaweed and used them to treat the types of lymphoma that are classified as being in the B-cell group.
"Some forms of B-cell lymphoma are especially resistant to standard treatment, and thus new therapies are needed," Mohammad Irhimeh, assistant professor of hematology/oncology and stem cells at the Hashemite University in Jordan, said in a news release from the American Association for Cancer Research.

Genetic Variant Raises Lung Cancer Risk
March 09, 2010
It doesn't matter whether you smoke a little or a lot, study finds. People with a particular genetic trait are at much higher risk of developing lung cancer from exposure to secondhand smoke than others, even if they rarely come into contact with it, a new study finds.
Researchers also found that smokers with this variant are more susceptible to lung cancer, whether they light up a lot or a little.
"If you carried the inherited risk and then you smoked, it didn't matter if you were a light smoker or a heavy smoker .

Blacks, Hispanics With Heart Failure Less Likely to Use Hospice
March 08, 2010
Despite increase in services, racial disparities persist, study finds.
Blacks and Hispanics with advanced heart failure are much less likely to turn to hospice care than whites, even though blacks in particular are more likely to develop the condition, a new report finds.
Heart failure, in which the heart weakens and can't beat effectively, is the second most common diagnosis for people in hospice care, which is designed for people with only months to live. Only cancer sends more people to hospice.

Proteins May Predict Spread of Colon Cancer
March 08, 2010
Discovery could lead to blood test that would aid prevention efforts, scientist says. Two proteins that might serve as biomarkers for predicting the spread of colon cancer have been identified by Chinese scientists.
They compared proteins produced by primary and metastatic colon cancer cells and found that two proteins occurred at much higher levels in the metastatic cancer cells than in the primary cancer cells.
Blood tests to check for the two proteins could help predict the spread of colon cancer, leading to earlier intervention and treatment, said researcher Maode Lai and colleagues.

New Prostate Cancer Guidelines Aim to Empower the Patient
March 05, 2010
Diagnostic test not infallible, can lead to unneeded treatments with unwanted side effects. New American Cancer Society guidelines on prostate cancer screening mean that many men will be faced with a cascade of decisions, with a growing responsibility for those decisions falling on their shoulders.
The guidelines, issued Wednesday, de-emphasize routine prostate-specific antigen (PSA) testing and re-emphasize the need for patient-doctor discussions on whether such tests are appropriate for individual patients.
PSA tests, which measure levels of a protein called prostate-specific antigen that's produced by the prostate gland, do detect cancers.

Radiation Most Effective Soon After Breast Cancer Surgery
March 04, 2010
Analysis finds greater risk of recurrence in those who delay radiotherapy. For women who have had breast cancer surgery, the question of whether or not to wait before receiving radiation therapy has been answered by new research that suggests that the longer women wait, the greater the chance of cancer recurrence.
The findings, published in the March 3 online edition of BMJ, are based on an analysis of national cancer records for 18,050 American women who were diagnosed with early-stage breast cancer between 1991 and 2002, at age 65 or older.
All of the women underwent breast-conserving surgery and radiation therapy, but not chemotherapy.

High Hormone Level Linked to Cancer Death in Older Men
March 03, 2010
More study needed to see if IGF-1 readings can predict risk. High levels of a hormone called insulin-like growth factor 1 (IGF-1) are associated with an increased risk of cancer death in older men, a new study has found.
The findings, published in the March issue of the Journal of Clinical Endocrinology & Metabolism, suggest that IGF-1 may prove a useful biomarker for predicting cancer risk.
IGF-1, which is similar in structure to insulin, is regulated by growth hormone.

Some Parents Consider Hastening a Sick Child's Death
March 01, 2010
Desire to save kids terminally ill with cancer from further pain prompts feelings, survey finds. Watching a child die of cancer is unimaginably heartbreaking for parents, and now a new survey shows that the urge to protect terminally ill children from any further pain led one in eight parents to consider hastening their child's death.
Researchers from the Dana-Farber Cancer Institute in Boston asked 141 parents of children who had died of cancer about their experiences at the end of the child's life.
About 13 percent of parents said they had considered asking caregivers about ending their child's life, and 9 percent actually had the discussion.

Reading Remediation Seems to Rewire the Brain
February 26, 2010
Study findings could have implications for autism, stroke and other conditions. Scientists studying the anatomy of children's brains during reading discovered something rather unexpected: Remedial training for poor readers results in a growth of white matter tracts in the brain, and the increase correlates with the level of improvement in sounding out words.
"This is the first evidence for an increase in white matter in response to a remedial behavioral intervention," said lead author Marcel Just, a psychology professor at Carnegie Mellon University in Pittsburgh and director of its Center for Cognitive Brain Imaging. "It provides evidence that repeated cognitive exercises can alter the cortical connectivity of the human brain.

Removing Lymph Nodes May Boost Endometrial Cancer Survival
February 25, 2010
For medium- to high-risk women, more surgery is better, study shows. Endometrial cancer patients at medium to high risk for cancer recurrence are more likely to survive if both the pelvic lymph nodes and para-aortic lymph nodes are removed, rather than just the pelvic lymph nodes, say Japanese researchers.
The para-aortic lymph nodes, which are located in front of the lumbar vertebral bodies near the aorta, receive drainage from the lower gastrointestinal tract and the pelvic organs, according to a news release about the study.
The study included 671 women with endometrial cancer who had pelvic lymph nodes removed or both pelvic and para-aortic lymph nodes removed.

Dry Weather Boosts Odds of Flu Outbreaks
February 23, 2010
Lower levels of water in cold winter air tied to more influenza, study suggests. Rain and snow may seem like perfect incubators for the flu, but new research suggests that low humidity and unusually dry skies might be responsible for increases in influenza, such as those that occur during winter months.
Previous research has suggested that humidity is connected to seasonal epidemics of flu, but studies have usually focused on relative humidity, as opposed to absolute humidity. Relative humidity, which varies with temperature, is the ratio of water vapor content in the air to the saturating level.

Information Gap Could Delay Lung Cancer Therapy in Blacks
February 22, 2010
More than half expect symptoms before diagnosis, survey finds. Black Americans are more likely than whites to have beliefs and perceptions about lung cancer that could interfere with prevention and treatment, new study findings suggest.
In the study, researchers analyzed the responses of 1,530 people who were asked questions related to lung cancer as part of the 2005 Health Information National Trends Survey.
The participants were asked if they agreed or disagreed with the following statements:
There's not much you can do to lower your chances of getting lung cancer
There are so many different recommendations about preventing lung cancer that it's hard to know which ones to follow
Lung cancer is often caused by a person's behavior or lifestyle
You are reluctant to get checked for lung cancer because you fear you may have it
Getting checked regularly increases chances of finding lung cancer when it is easy to treat
People with lung cancer have pain or other symptoms prior to diagnosis
The majority of participants, both black and white, did not believe they were at high risk for lung cancer, and many greatly overestimated the survival of lung cancer, the study found.

Pediatricians Want Redesign of Hot Dogs, Candy to Curb Kids' Choking
February 22, 2010
New AAP policy also pushes for warning labels on packaging of high-risk foods. The leading group of pediatricians in the United States is pushing for a redesign of common foods such as hot dogs and candies, along with new warning labels placed on food packaging, to help curb sometimes fatal incidents of child choking.
"We know what shape, sizes and consistencies pose the greatest risk for choking in children and whenever possible food manufacturers should design foods to avoid those characteristics, or redesign existing foods when possible, to change those characteristics to reduce the choking risk," said Dr. Gary Smith, immediate-past chairman of the American Academy of Pediatrics' Committee on Injury, Violence and Poison Prevention and lead author of the organization's new policy statement on preventing choking.

Two Surgical Methods Equally Successful for Prostate Cancer
February 22, 2010
Comparison study of open and laparoscopic surgery found few differences in outcome. Results are similar for men with prostate cancer whether they have open surgery or laparoscopic surgery, a new study has found.
Currently, open radical prostatectomy (ORP) is considered the standard treatment but the use of laparoscopic radical prostatectomy (LRP), with or without robotic assistance, is becoming more widespread.
In the new study, researchers at Memorial Sloan-Kettering Cancer Center in New York City compared ORP and LRP outcomes in nearly 6,000 men, age 66 or older, with localized prostate cancer.

High Rates of Childhood Leukemia Seen in Iraq Province
February 18, 2010
Cases in Basra more than doubled over 15 years, research shows. Childhood leukemia rates more than doubled in a southern Iraq province over a 15-year period, although the exact cause for the increase is unclear, researchers say.
Possible reasons why so many kids in the province of Basra became ill include exposure to chemicals from petroleum fires, gasoline sold by children on the side of the road, chemical weapons and pesticides, the authors of the new study noted.
Researchers at the University of Washington in Seattle found 698 documented cases of leukemia in the province among children under the age of 15 during the period between 1993 and 2007.

Screens, Vaccine for HPV Less Beneficial in Older Women
February 18, 2010
Rate of new infections declined with age, study found. As women age, they receive fewer benefits from frequent screening for human papillomavirus (HPV) and vaccinations to prevent the virus, new research shows.
While infection with certain types of HPV can lead to cervical cancer, there is a vaccine that can help protect against many of these HPV infections.
However, this study of Costa Rican women, aged 18 to 97, concluded that the benefits of HPV vaccination and screening are low among women over the age of 41.

Kidneys From Older Donors Suitable for Seniors
February 18, 2010
More could be transplanted if doctors would put them on the list, study suggests. Too many American seniors who need a new kidney have to wait longer than necessary for a transplant, researchers say.
In a new study, Johns Hopkins researchers analyzed kidney donation data from 2003-2008 and found that one-third of patients over age 65 experience unnecessary delays because their doctors don't put them on a list for kidneys from older donors (extended-criteria donors, or ECDs) that are unsuitable for younger patients but perfectly fine for older patients.
The findings were published online in the American Journal of Transplantation.

Minorities Not Treated at Higher-Quality Centers
February 15, 2010
Study urges added effort to inform all patients about comparative data. Minority patients in New York City receive less specialized surgical care than white patients, according to a new study.
Specifically, Yale University researchers found that minorities were less likely to have an operation performed by surgeons, and were less prone to getting cared for at facilities that performed a large number of similar procedures.
The study included almost 134,000 people who had one of 10 procedures in which the number of such surgeries performed by a surgeon or at a hospital is known to influence patients' short-term risk of death.

Wedding Band Makes Jealousy a Bigger Threat
February 12, 2010
Study found distrust much more damaging in marriage than in other relationships. Jealousy can dampen romance and damage sexual intimacy, especially if it occurs within a marriage, says new research that serves as a caution for couples as Valentine's Day approaches.
"Being married may 'up the ante,' because marriages tend to have higher levels of relationship commitment and joint investments [such as children, leisure, property and social networks]," said study co-author Anthony Paik, an assistant professor in the sociology department at the University of Iowa.
The study, published in a recent issue of the Journal of Sex Research, found that if jealousy wasn't a factor, three out of every four married people were highly satisfied with the emotional facets of their marriage.

ADHD Brain May Be a Little Different
February 11, 2010
Ventral striatum is smaller, which may explain impulsiveness, researchers say. A link appears to exist between attention-deficit hyperactivity disorder (ADHD) and anomalies in the brain's reward system, a new study suggests.
Spanish researchers used MRI to scan the brains of 42 children with ADHD and 42 other children with no signs of ADHD and found that the ventral striatum was smaller, particularly on the right side, in those with ADHD. The ventral striatum includes the nucleus accumbens, which maintains levels of motivation when a person starts a task and continues to maintain motivation until the task is completed.

Medicare Cost-Saving Moves Can Backfire
February 09, 2010
Upping payments for bladder biopsies done in doctor's office boosted overall spending, study found. After Medicare sweetened payments for simple office-based endoscopic procedures, doctors in one New York City practice performed many more in-office bladder biopsies, but the volume of hospital procedures stayed roughly the same, a new study finds.
So, instead of saving money, Medicare expenditures rose 50 percent after the U.S.

Inflammatory Bowel Ups Risk for Blood Clots
February 09, 2010
Doctors should consider preventive measures, study suggests. People with active inflammatory bowel disease are much more likely to develop blood clots than people without the condition, a new study suggests.
And that may make preventive drug treatment necessary, it adds.
The study, done in the United Kingdom, compared data on 13,756 people who had inflammatory bowel disease (IBD) with 71,672 people who did not have it.

Paxil Blocks Tamoxifen, Lowers Survival Odds Against Breast Cancer
February 09, 2010
Patients should avoid taking the two drugs together, researchers say. Women with breast cancer who take both tamoxifen and the antidepressant Paxil may increase their risk of dying because Paxil reduces tamoxifen's effectiveness, Canadian researchers report.
"Paxil can deprive women of the benefit of tamoxifen, especially when it is used in combination with tamoxifen for a long time," said lead researcher Dr. David Juurlink, division head of clinical pharmacology and toxicology at Sunnybrook Health Sciences Center in Toronto.

Intensive Rectal Cancer Treatment Shows Promise
January 26, 2010
Tumors were downstaged in most patients following chemo-surgery regimen, researchers say. An intensive treatment strategy shows promise against locally advanced rectal cancer.
The phase 2 study included 105 patients with poor-risk rectal cancer, meaning they have a high likelihood of disease recurrence and poor survival odds despite receiving standard chemotherapy and optimum surgery.
For this study, the patients underwent 12 weeks of chemotherapy treatment with capecitabine and oxaliplatin, followed by chemoradiotherapy with capecitabine and surgery, followed by another 12 weeks of capecitabine treatment.

Discovery Links Genes to Pancreatic Cancer
January 25, 2010
Researchers must still determine how to use the data to reduce risk. Researchers have identified four regions of the human genome that predict a heightened risk of pancreatic cancer as a result of what they describe as the biggest-ever sweep of the genome for genes related to the disease.
Though some of the locations had been linked to other cancers, the discovery of others apparently surprised the researchers.
"This lets us go places we had never thought of before," said senior study author Dr.

Male Abusers Often Sabotage Birth Control With Partners
January 25, 2010
Study found physical violence often accompanied by attempts to get young women pregnant. A new report says that male partners of teenage girls and young women who engage in physical and sexual violence also often try to sabotage the birth control the women are using.
The study, which appears online in the January issue of Contraception, also finds that women who experience both birth-control sabotage and violence from their partner are twice as likely to have an unintended pregnancy.
"This study highlights an under-recognized phenomenon where male partners actively attempt to promote pregnancy against the will of their female partners," study author Elizabeth Miller, an assistant professor of pediatrics in the University of California at Davis School of Medicine, said in a news release from the school.

Self-Image Linked to Activity in Frontal Lobe of Brain
January 23, 2010
People with high self-regard use brain area less, MRI scans show. People who have an unrealistically high opinion of themselves have less activity in the frontal lobes of their brain, researchers have found.
"In healthy people, the more you activate a portion of your frontal lobes, the more accurate your view of yourself is. And the more you view yourself as desirable or better than your peers, the less you use those lobes," Jennifer Beer, an assistant professor of psychology at the University of Texas at Austin, said in a university news release.

Obesity Tied to Common Kidney Cancer
January 22, 2010
Odds of having clear-cell renal cell cancer jump as body mass increases, study finds. Obesity increases the risk of developing a common and virulent form of kidney cancer, a new study finds.
Researchers looked at 1,640 patients, average age 62, with kidney tumors and found that obese patients were 48 percent more likely to develop a clear-cell renal cell cancer (RCC) than those with a body-mass index(BMI) of less than 30, the cutoff for obesity. The odds of developing RCC increased by 4 percent for every extra BMI point.

Gene Variation May Speed Recurrence of Stomach Cancer
January 22, 2010
Disease returned three times sooner in study participants with inherited trait. An inherited genetic trait may be linked to more aggressive cases of stomach cancer, researchers say.
The new findings don't prove that the gene variation actually causes stomach cancer, also known as gastric cancer, but those who have the variation, which is found on a gene called CD44, experienced recurrence of the disease more than three times sooner than others with the disease.
The findings are scheduled to be presented Friday at the Gastrointestinal Cancers Symposium in Orlando, Fla.

Vitamin D May Lower Colon Cancer Risk
January 22, 2010
The higher the level in blood tests, the less likely the disease, study finds. High levels of vitamin D in the blood appear to be linked to lower risks of colorectal cancer, although it's not clear if higher intake of the vitamin actually prevents the disease, researchers say.
Still, the findings are food for thought: Scientists found that those with the highest levels of vitamin D in their blood had as much as a 40 percent lower risk for developing colorectal cancer than those with the lowest levels.

Radiation Dose Lower With Digital Mammography
January 21, 2010
Compared to conventional film, new method reduces exposure, research shows. Digital mammography delivers significantly less radiation than conventional mammography, and the reduction in radiation exposure may be greater for women with larger and denser breasts, a new study has found.
In the study, researchers analyzed data from 5,102 women who received both digital and standard film mammography.
According to the findings, published in the February issue of the American Journal of Roentgenology, the average breast radiation dose per view was 22 percent lower for digital than film mammography.

Blacks Often Misdiagnosed With Schizophrenia, Author Says
January 15, 2010
Trend dates to Civil Rights era and continues today, new book claims. Black men in the United States are misdiagnosed with schizophrenia at least five times more often than any other racial group.
This trend dates back to the 1960s and 1970s, when equal rights activism was equated with mental illness, said researcher Jonathan Metzl, an associate professor of psychiatry and women's studies at the University of Michigan, and director of U-M's Culture, Health and Medicine Program.
He analyzed archives at the Ionia State Hospital for the Criminally Insane and found that black men, mainly from Detroit during the civil rights era, were taken to the facility and often misdiagnosed with schizophrenia.

Incorrect Cell Lines Used for Worldwide Cancer Research
January 14, 2010
But tumor-type mixups don't necessarily negate findings, experts say. Cancer researchers rely on specific tumor cell lines when developing new treatments, but those samples aren't always what they're advertised to be, a Dutch team reports.
Their study found that three of 13 human esophageal cancer cell lines widely used for worldwide research were actually cell lines from lung, colorectal and other malignancies.
Two of the contaminated or misidentified cell lines were involved in research published in more than 100 papers and in the issuance of 11 U.

With Pancreatic Cancer, Age Factors Into Familial Risk
January 12, 2010
Having relative diagnosed before 50 adds to likelihood of diagnosis, study finds. People with a family member who had pancreatic cancer before age 50 face a greatly increased risk for the disease, a new study has found.
Researchers already knew that people with several relatives diagnosed with pancreatic cancer were more likely than others to develop the disease, but it wasn't clear whether the relatives' age when they got the disease played any role.
They found, though, that risk increased ninefold when just one of several family members with the disease developed it before turning 50.

Green Tea May Lower Lung Cancer Risk
January 12, 2010
Benefits seen for smokers, nonsmokers, those with certain genetic makeup. Antioxidants in green tea appear to significantly lower the risk for developing lung cancer among smokers and nonsmokers alike, new research from Taiwan reveals.
The study suggests that smokers and nonsmokers who consume a minimum of one cup of green tea per day appear to have a nearly 13-fold and fivefold lower risk, respectively, for developing lung cancer than smokers and nonsmokers who don't drink any green tea.
"The health effect of green tea consumption could modify the risk of lung cancer, particularly among smokers," said study author I-Hsin Lin, of Chung Shan Medical University in Taichung.

Doctors Put Off End-of-Life Talks With Terminally Ill
January 12, 2010
Frank conversations about hospice and preferred place of death are often needed, experts say. Terminally ill patients have much to consider, from whether they want to die at home or in the hospital to whether they want doctors to continue aggressive treatment or focus on making them comfortable during their final weeks or months.
Yet those difficult, emotional conversations aren't happening nearly as often, or as early, as they ought to be, say researchers who surveyed a national sample of almost 4,100 physicians who treat cancer patients.
Given a hypothetical example of a cancer patient with four to six months to live but who was still feeling well, 65 percent said they would discuss a prognosis.

Genetic Marker for Aggressive Prostate Cancer Found
January 11, 2010
Variant could be used to guide treatment, researchers suggest. A focused search of the entire human genome has found a genetic variant associated with the aggressiveness of prostate cancer, in a discovery that marks an important first step toward singling out cancers that need intensive treatment from those that can simply be left alone.
"It is a proof of principle to show that there are variants in the genome that influence the different kinds of prostate cancer," said Dr. Jianfeng Xu, a professor of epidemiology and cancer biology at Wake Forest University Baptist Medical Center, and leader of a team reporting the finding online in the Jan.

Rheumatoid Arthritis Drug Lowers Flu Shot Effectiveness
January 11, 2010
But patients should still get vaccinated, researchers say. New research offers a caution to rheumatoid arthritis patients who take the drug rituximab (Rituxan): The flu vaccine is safe, but it's ineffective during the first six months following treatment with Rituxan.
The researchers also found that previous flu vaccination does help provide some protection against the flu, and the vaccine won't make the arthritis symptoms worse.
The study findings are published in the January issue of Arthritis & Rheumatism.

Short School Closures Won't Shut Down Flu
January 08, 2010
Two-week shutdowns won't work, simulations suggest. Schools need to be closed for at least eight weeks during an influenza epidemic to significantly reduce infection rates, according to a new study.
Closing schools for less than two weeks, it found, has little effect.
The findings stem from a series of computer simulations of flu transmission in Allegheny County, Pa.

Stored Fats May Make Cancer Cells More Aggressive
January 07, 2010
Finding could explain link between obesity and cancer, researchers say. An enzyme that normally helps break down stored fats becomes highly active in some cancer cells and makes them more likely to spread, researchers have found.
When the enzyme, called monoacylglycerol lipase (MAGL), goes into overdrive in cancer cells, it breaks down stored fats to produce large amounts of free fatty acids, which are the building blocks of cell membranes and of fatty molecules that serve as signals between cells. These free fatty acids then produce other smaller molecules that promote cancer growth and progression, the study authors noted.

Calorie Counts on Food Labeling Often Off
January 07, 2010
Restaurant and packaged foods often have more calories than stated, researchers say. Many reduced-calorie restaurant and packaged foods in the United States have more calories than indicated on their nutritional labeling, a new study reports.
Tufts University researchers analyzed 29 quick-serve and sit-down restaurant foods and found they contained an average of 18 percent more calories than the stated values. The team also checked 10 frozen meals bought from supermarkets and found they had an average of 8 percent more calories than what was printed on the label.

Lower Vitamin D Levels in Blacks May Up Heart Risks
January 06, 2010
Darker skin reduces absorption of sunlight, researchers explain. New research indicates that the darker skin of blacks may increase their risk of heart disease and stroke because it reduces production of vitamin D, which is made during exposure to sunlight.
Several studies have associated low levels of vitamin D with an increased risk of cardiovascular disease and "the biggest source of vitamin D levels is sunlight," said Dr. Kevin Fiscella, a professor of family medicine and community and preventive medicine at the University of Rochester, and co-author of a paper in the January/February issue of the Annals of Family Medicine.

Insect Cells Instead of Eggs for Swine Flu Vaccine?
January 06, 2010
Novel method is faster and avoids allergy issues, researchers say. A method that uses insect cell-based technology produces vaccines for swine flu faster than traditional egg-based vaccine production, say Austrian scientists.
Using this new approach, the researchers created recombinant influenza virus-like particles (VLPs) in just 10 weeks, rather than the months it takes using conventional production methods. VLPs resemble virus particles but aren't infectious because they lack the viral nucleic acid.

Markers for Ovarian Cancer May Show Up Years Earlier
January 05, 2010
Blood tests detect changes from 12 to 36 months before diagnosis, study finds. Concentrations of several biomarkers begin to grow three years before women are diagnosed with ovarian cancer, but only reach substantial elevation levels over the 12 months before diagnosis, new research finds.
The findings, published online in the Journal of the National Cancer Institute, expand on previous research into biomarkers known as CA125, HE4, mesothelin, B7-H4, decoy receptor 3 and spondin-2.
Researchers from Fred Hutchinson Cancer Research Center in Seattle examined blood serum samples from a lung cancer study.

Experimental Drug May Help in Brain, Prostate Cancers
January 04, 2010
Study finds that imetelstat targets mechanism that allows cancer cells to divide. An experimental drug called imetelstat shows promise in treating glioblastoma brain cancer and prostate cancer, according to the results of preclinical studies in which the drug was tested on human prostate cancer cells and in rodents with glioblastoma.
Researchers from the University of Texas Southwestern Medical Center found that the drug had an effect on most tumor cells, as well as cancer stem cells believed to cause most of a cancer's growth. Tests in mice with glioblastoma also showed that the drug was able to cross from the bloodstream into the brain.

Key Protein Could Put Brakes on Cancer's Blood Supply
January 04, 2010
Lowering delta-catenin levels may safely slow tumor growth, scientists say. Researchers report they stopped the growth of blood vessels that are crucial to tumor survival by lowering the level of a protein found in brain cells.
The protein, known as delta-catenin, is known for its effects on the growth of the brain cells called neurons, but is also produced by cells in human blood vessels. Researchers found that they could disrupt the development of blood vessels that are connected to tumors and wounds by diminishing levels of the protein.

Clues to Cancer That Could Wipe Out Tasmanian Devils
December 31, 2009
Researchers are working on genetic puzzle to try to save the mammals. Researchers are gaining a better understanding of an outbreak of cancerous tumors that is killing many of Australia's Tasmanian devils, according to a new report.
Devil facial tumor disease, a kind of cancer that's spread from animal to animal through biting or other physical contact, is one of only two types of cancer known to be transmitted in this way through living cancer cells (the other such cancer is in dogs). The disease, which quickly kills the animals, starts out as large tumors on the face and mouth, but then can spread to the animals' internal organs.

Stem Cells Might Reverse Heart Damage From Chemo
December 30, 2009
Cancer patients could one day take potent therapies, get heart fixed later, researchers say. Certain types of chemotherapy can damage the heart while thwarting cancer, a dilemma that has vexed scientists for years. But a new study in rats finds that injecting the heart with stem cells can reverse the damage caused by a potent anti-cancer drug.
The findings could one day mean that cancer patients could safely take higher doses of a powerful class of chemotherapy drugs and have any resulting damage to their hearts repaired later on using their own cardiac stem cells, the researchers said.

Doctors routinely ask that men come back to ensure effectiveness, but many don't, study finds. Nearly half of men who get vasectomies don't return for follow-up tests that make sure the procedure is working, new research suggests.
Those who don't go back, and therefore risk an unwanted pregnancy, are more likely to be smokers, not highly educated and the fathers of four or more children, the study found.
The findings show the need for better communication between doctors and vasectomy patients, especially those at higher risk of not following up, said study co-author Yefim Sheynkin, an associate professor of urology at the State University of New York at Stony Brook.

Alzheimer's May Stave Off Cancer, and Vice Versa
December 23, 2009
Biological factors that lead to one seem to protect against the other, expert says. Researchers have uncovered a bittersweet relationship between two major illnesses: cancer and Alzheimer's disease.
People who have had cancer are less likely to get Alzheimer's disease, just as having Alzheimer's disease reduces the risk for cancer, their study found.
"Alzheimer's was associated with a rather dramatic reduction in cancer risk," said Dr.

Nearly 5 Million Doses of Nasal Swine Flu Vaccine Recalled
December 23, 2009
Tests reveal slight drop in potency, but not enough to require revaccination, FDA says. Nearly 5 million doses of a nasal spray version of swine flu vaccine have been recalled because the vaccine loses some potency over time, but not enough to diminish its protective effect, U.S. health officials announced Tuesday.
Melanoma Less Common in Blacks But Deadlier
December 23, 2009
Skin cancer diagnosis occurs later in nonwhites, study finds. Doctors are diagnosing more white people with the deadly skin cancer known as melanoma, and while Hispanics and blacks are much less likely to be diagnosed with the malignancy, they often have advanced forms of the cancer when it is found, new research suggests.
"Research and public education efforts have focused on melanoma prevention in white populations because of their higher risk of developing melanoma," the study authors wrote in the December issue of the Archives of Dermatology. "Improved secondary prevention measures with earlier detection of thin [early-stage] melanoma likely account for the improved survival among whites from 68 percent in the early 1970s to 92 percent in recent years.

Patient Factors Mar Accuracy of Multi-Detector CT Scans
December 22, 2009
Image quality varies due to ethnicity, weight, heart rate, study finds. A type of computed tomography scan used to detect coronary artery disease can be affected by factors such as a patient's ethnicity, height/weight ratio and heart rate, researchers have found.
The scanning technology at issue is known as multi-detector computed tomography (MDCT). In the new international study, researchers looked at scans of 291 patients with clogged arteries and found that images from black patients had poorer quality than those from white patients.

Blacks Have Less 'Bad Fat' Than Whites
December 18, 2009
It's a puzzle, because less visceral fat should mean less obesity-linked disease, experts say. Blacks tend to carry around less of a particularly unhealthy type of abdominal fat than whites, even though they suffer more from obesity-linked illness, researchers report.
The new finding suggests that body-mass index (BMI) guidelines may need to be tailored to specific racial groups to better reflect risk, experts say.
"The study clearly shows we have these racial differences in body fat, not just in the type of body fat but where the fat is stored, and these are important differences," said study author Peter Katzmarzyk, a professor of population science at Pennington Biomedical Research Center in Baton Rouge, La.

Spiritual Needs Rank High as Death From Cancer Nears
December 18, 2009
Being 'at peace with God' affects medical choices, study finds. Addressing the spiritual needs of someone with advanced cancer could be just as important as taking care of their medical needs, a new study suggests.
When asked what was important to them at the end of their lives, people dying of cancer ranked two factors highest: pain control and being at peace with God, the study found.
"Medicine tends to focus on the more scientific aspects of the person, and we've made wonderful strides in improving patient care, but there's another important component of patient health: spirituality," explained Dr.

Scientists Link Molecule to Severe Swine Flu
December 17, 2009
Blocking the particle might someday ease accompanying lung infections. Some people develop severe pneumonia when infected with the swine flu virus, and researchers say they've found a clue as to why.
A key to the severity of the illness appears to be a molecule called interleukin 17 (TH17), which helps the immune system fight off germs and disease. Researchers who analyzed levels of the molecule in swine-flu patients at 10 Spanish hospitals last summer found the highest levels in the blood of those with severe illness and the lowest in people with milder forms of the disease.

Physical Activity May Prolong Survival After Colon Cancer
December 14, 2009
Exercise benefited men whose disease had been treated, hadn't spread, study finds. Exercise appears to reduce the risk of death in male colon cancer survivors, researchers report.
The study, which began in January 1986, included 668 men who'd been treated for stage I, stage II or stage III colon cancer that had not spread (nonmetastatic cancer). Every two years, the men were sent questionnaires that asked them about any new cancer and disease diagnoses, as well as their physical activity.

Chemo With Herceptin May Be Best for Some Breast Cancers
December 13, 2009
Taking the drug during chemotherapy, rather than after, improves survival, study finds. New research suggests that certain breast cancer patients who take the drug Herceptin during chemotherapy, instead of taking it afterward, fare better, leading one of the study authors to say patients should routinely take the drug with chemo.
The patients at issue are those with HER2-positive breast cancer, which accounts for 20 percent to 25 percent of all cases of the disease.
Researchers looked at the outcomes for hundreds of women who underwent different treatment regimens.

Tweaks to Breast Cancer Treatments Boost Outcomes
December 12, 2009
In one study, longer Herceptin use helped beat back the disease. With a growing array of choices for breast cancer treatment, researchers are now trying to pinpoint the best combination of therapies or the best order in which to give cancer drugs to patients.
In some cases, combination therapies will improve survival and sometimes the order in which therapies are given does not matter, said experts presenting new data at a Friday press briefing at the San Antonio Breast Cancer Symposium.
"The most dramatic finding [presented at the briefing] is that continuing Herceptin therapy after tumor progression improves survival," said moderator Dr.

Review Questions Tamiflu's Effectiveness
December 08, 2009
Finds no proof the drug prevents flu complications such as pneumonia. No evidence exists that the widely used influenza drug Tamiflu prevents pneumonia or other complications in otherwise healthy patients who come down with the flu, a new review contends.
Claims about the effectiveness of the antiviral drug against flu-related complications have influenced governments worldwide to stockpile Tamiflu (oseltamivir) as part of their preparations for a global pandemic, the review authors said.
"Governments around the world have spent billions of [dollars] on a drug that the scientific community now finds itself unable to judge," said Dr.

Coffee, Exercise Fight Prostate Cancer
December 08, 2009
Studies show improved survival among men who partake regularly. Having a few more cups of coffee and running that extra mile each day can reduce a man's risk of dying of prostate cancer, two studies indicate.
The case for coffee and physical activity as prostate cancer preventatives is far from proven, according to the research reported Tuesday at an American Association for Cancer Research meeting in Houston. But data from the Health Professionals Follow-Up Study show a clear association with both daily activities.

Breast Cancer Decline Only Partly Due to HRT
December 08, 2009
Drop in hormone replacement therapy doesn't fully explain the 7% falloff, researchers say. The incidence of breast cancer in the United States declined 7 percent between 2002 and 2003, but only part of that decrease can be attributed to reduced use of hormone replacement therapy (HRT) by menopausal women, researchers say.
HRT use declined after the 2002 release of The Women's Health Initiative study, which concluded that hormone therapy increases the risk of breast cancer. Other studies have confirmed the link.

Prostate Hormone Therapy May Up Heart Risks
December 07, 2009
Experts urge more awareness that long-term use has consequences. Diabetes, heart attacks and other cardiovascular problems appear to be more common in men with prostate cancer who are treated with androgen deprivation therapy, which reduces or eliminates the male sex hormones that can promote cancer growth, a new study has found.
The finding indicates that androgen therapy is overused because its benefits have not been shown to outweigh its dangers in many cases, said Dr. Nancy L.

U.S. Cancer Cases, Deaths Continue to Drop
December 08, 2009
Report says lifestyle changes, better screening and treatment explain decrease. Better screening, healthier living and new treatments have all continued to help cut the annual number of cancer cases and deaths in the United States, a new report says.
The findings showed that new cancer cases and deaths from cancer have declined significantly for both men and women and for most racial/ethnic populations.
These decreases were largely due to decreased incidence and death from lung, prostate and colon cancer among men and a drop in two of the three leading cancers in women (breast and colon cancers).

Swine Flu Can Batter Kids With Sickle Cell
December 07, 2009
Children with the disease should be vaccinated along with other high-risk groups, researchers say. Swine flu is more likely than seasonal flu to cause life-threatening complications in children with sickle cell disease, a new study has found.
Johns Hopkins Children's Center researchers analyzed the medical records of 118 children with sickle cell disease treated for any kind of flu between September 1993 and November 2009. Of those patients, 28 were infected with the H1N1 (swine flu) virus, which emerged last April.

New Target May Be Eyed in Kids' Brain Cancer
December 07, 2009
Scientists closer to understanding the development of deadly neuroectodermal tumors. Scientists have identified oncogenes that play a role in a particularly aggressive type of childhood brain tumor.
Known as central nervous system primitive neuroectodermal tumors (CNS-PNETs), the discovery of these oncogenes may lead to improved diagnosis and treatment of the deadly condition.
"Lack of insight into the molecular pathogenesis of CNS-PNET is a major obstacle towards development of disease-specific models and treatments for these frequently fatal malignancies," noted senior study author Dr.

Parents, children need to discuss sexual matters sooner, researchers say. When it comes to talking about sex, parents are a few paces behind their kids.
Too often, the birds-and-the-bees conversation occurs after, and not before, kids start experimenting sexually, possibly in risky ways, reports a study in the January issue of Pediatrics.
This revelation comes despite American Academy of Pediatrics recommendations that health-care providers and parents talk to their kids about sex and sexuality early in life.

Hormonal Drugs Cool Hot Flashes From Prostate Cancer Therapy
December 07, 2009
Medroxyprogesterone wins out in comparison study. Hot flashes caused by androgen suppression therapy for prostate cancer are best controlled by the hormonal treatments cyproterone acetate and medroxyprogesterone acetate, according to a new study.
Androgen suppression is considered the gold standard treatment for advanced prostate cancer, but about 80 percent of patients undergoing the treatment experience hot flashes. A number of hormonal and non-hormonal drugs are used to treat the hot flashes, but no direct comparisons of the drugs have been made in clinical trials.

Breast Cancer's Spread Now Better Understood
December 07, 2009
Findings offer hope for future treatments targeting growth factor, researchers say. The spread of breast cancer cells from the main tumor to other parts of the body is controlled by a growth factor known as TGFb, which may prove a promising target for new drugs to prevent metastatic breast cancer, British researchers say.
Previous studies have shown that TGFb (transforming growth factor beta) regulates normal cell growth and movement. In this new study, a team from Cancer Research UK used an advanced microscopy and analysis technique to document the movement of cancer cells from primary breast tumor sites in mice.

High-Risk Women May Often Avoid Using Tamoxifen
December 04, 2009
Armed with knowledge of risks, many hesitate to take breast cancer drug, study finds. Worries about side effects are a major reason why only 6 percent of American women at high risk for breast cancer are willing to take the drug tamoxifen to prevent the disease, a new study finds.
In an effort to inform women about the risks and benefits of tamoxifen, researchers at the University of Michigan Comprehensive Cancer Center created a decision aid, which was tailored to the health history of each of the 632 women in the study.
"That means, when women read this decision aid, they learned about how the drug was likely to affect them given their age, race, breast cancer history and medical history," study author Angela Fagerlin, an associate professor of internal medicine at the University of Michigan Medical School and a research investigator at the VA Ann Arbor Healthcare System, said in a university news release.

November 24, 2009
Patients who had at least one child were less likely to become disabled, study finds. Having children may slow the progression of multiple sclerosis, new research suggests.
Belgian researchers followed 330 women who had experienced their first MS symptoms between the ages of 22 and 38.
Women who had given birth to at least one child were 34 percent less likely to have the disease progress to a stage in which they needed walking assistance, such as a cane or brace, than women without children.

Stifled Anger at Work Doubles Men's Risk for Heart Attack
November 24, 2009
More open on-the-job interaction might ease the problem, researchers say. Men who bottle up their anger over unfair treatment at work could be hurting their hearts, a new Swedish study indicates.
Men who consistently failed to express their resentment over conflicts with a fellow worker or supervisor were more than twice as likely to have a heart attack or die of heart disease as those who vented their anger, claims a report in the Nov. 24 online edition of the Journal of Epidemiology and Community Health.

Women Should Ignore New Mammogram Guideline, Ex-NIH Chief Says
November 23, 2009
Dr. Bernadine Healy, first woman to head the agency, said lives could be at risk. The fallout from last week's controversial recommendation that women delay the start of routine mammogram testing for breast cancer continues, with a former head of the U.S. National Institutes of Health advising women to ignore the guidelines.
Vioxx Problems Known Years Before Recall
November 23, 2009
Study points up weaknesses of drug approval process in United States, researcher says. Problems with the popular arthritis drug Vioxx, including increased risk for heart attack, stroke and death, were known for years before the drug's voluntary withdrawal from the market in 2004, a new report says.
Contrary to claims by the manufacturer, Merck & Co., dangerous side effects were evident in 2000, a year after the drug was put on sale, but independent investigators lacked access to all the clinical trial data, so no one voiced concerns until four years later, say the authors of the latest look at the controversy.

Sleep Disorders Plague Cancer Patients
November 23, 2009
More than three-quarters getting chemo deal with insomnia, study shows. Insomnia and sleep disorders affect more than three-quarters of cancer patients undergoing chemotherapy, a rate nearly three times higher than that of the general population, a new study finds.
The problem is more common in younger patients and in those with lung and breast cancers, said University of Rochester Medical Center researchers, who assessed sleep problems in 823 cancer patients.
Questionnaires completed by patients after their first two chemotherapy treatments revealed that 37 percent suffered from insomnia symptoms and another 43 percent had insomnia syndrome, which means they had difficulty falling asleep and staying asleep at least three nights per week, the researchers reported in the Nov.

Quick Saliva Test May One Day Diagnose Diseases
November 23, 2009
Age-related protein changes offer clues to treatment advances, study finds. The protein content of saliva changes as people age, and better understanding of these changes may help lead to a simple test to diagnose and treat age-related diseases, researchers suggest.
Human saliva contains numerous proteins that play a role in digestion, fighting diseases and other functions. Researchers are trying to find ways to use these proteins to develop quick tests to assess a person's health.

Co-existing illnesses also don't explain why more blacks die than whites, study finds. Body weight and co-existing health problems don't explain why black colon cancer patients have lower survival rates than whites, U.S. researchers say.
Text Messages Might Increase Sunscreen Usage
November 20, 2009
With daily reminders, people may be more apt to protect their skin. Sunscreen can help reduce the risk of skin cancer, but people forget to apply it. Now, researchers say, daily text-message reminders could increase usage.
Researchers from the University of California-Davis Health System, in Sacramento, recruited 70 adults and randomly assigned half of them to get text messages that included information about local weather and a reminder to wear sunscreen.

Swine Flu May Hit Kids With Asthma Harder
November 20, 2009
Canadian study finds more severe cases than with seasonal flu. Canadian researchers are reporting that children with asthma are more likely to develop severe cases of H1N1 flu than seasonal flu.
"Asthma has been identified as a significant risk factor for admission with pandemic H1N1 influenza, present in 21 percent to 30 percent in the larger samples," wrote Dr. Upton Allen and fellow researchers from the Hospital for Sick Children in Toronto.

Blood Test Could Boost Clarity of Breast MRI Results for Some
November 20, 2009
Taking menstrual cycle into account when booking exam may cut need for repeat scans, study suggests. Using a blood test to pinpoint the optimal timing of breast MRI scans in women with irregular menstrual cycles could reduce the need for repeat scans, U.S. researchers say.
Discovery Boosts Boys' Prospects for Post-Cancer Fertility
November 20, 2009
Testicular cells could be preserved for later use, study suggests. New research suggests it may become possible for pre-pubescent boys stricken by cancer to prepare for the future when they may be infertile but still want to become natural fathers.
Scientists in the Netherlands found that testicular stem cells can be cultured and multiplied, potentially creating sperm. This raises the prospect that men made infertile by childhood cancer treatments could impregnate women by having the cells implanted in their testicles.

No Immediate Changes Expected in Mammogram Coverage
November 20, 2009
Health plans say routine screening is an individual decision. Women can rest assured, at least for now, that their health plan will continue to pay for an annual mammogram beginning at age 40.
A firestorm set off this week by a federal task force recommendation against "routine screening" of women under 50 is not likely to spur hasty changes in coverage policies, experts say.
"We're not hearing that coverage is going to change.

Great American Smokeout '09
Time to Quit
November 19, 2009
American Cancer Society sets Nov. 19 as annual day to 'butt out' for good. The less you smoke, the more birthdays you'll have, says the American Cancer Society as it encourages smokers to quit on Thursday, the day of the 34th Great American Smokeout.
Research shows that smokers who quit at age 35 gain an average of eight years of life expectancy, and those who quit at 55 gain about five years. Even long-time smokers who quit at age 65 gain three years.

Genital Herpes May Never Go Dormant
November 18, 2009
Study finds low level shedding may be continuous, infection state unclear. Herpes, the sexually transmitted disease that causes genital lesions, never truly goes into a dormant state, new research suggests.
As a matter of fact, even when it's not causing an outbreak, the virus is shedding tiny bits of itself in the genital tract.
While the study did not specifically address whether or not the very small amounts of virus being continually shed are enough to infect someone else, the findings have the potential to change the way in which scientists view the life cycle of the disease.

MS Need Not Preclude Pregnancy
November 18, 2009
Study finds complications no greater overall than for other women. New research suggests that having multiple sclerosis puts pregnant women at slightly higher risk for giving birth via cesarean deliveries or having babies that grow at a slower rate in the womb.
But the researchers, whose findings were published online Nov. 18 in Neurology, also reported that pregnant women with MS were not more likely than other women to develop such conditions as preeclampsia or premature rupture of membranes.

Combination can increase the risk of heart attack and stroke, U.S. officials say. Combining the antacid Prilosec with the popular blood thinner Plavix (clopidogrel) can cut the effectiveness of Plavix by half, putting patients at risk for heart attack or stroke, U.S. health officials said Tuesday.
Folic Acid Fortification Might Boost Cancer Risk
November 17, 2009
Norwegian study found supplementation raised chances of disease by 21%. Although folic acid fortification of foods can prevent many birth defects, it may also increase the risk for developing cancer, Norwegian researchers report.
Since 1998, many countries have mandated folic acid (vitamin B9) fortification of foods to decrease the incidence of neural-tube defects in newborns. By October 2009, the flour produced in these countries, plus the flour that is fortified voluntarily, represented 30 percent of the world's wheat flour produced in large mills.

Guidelines Delay Start of Mammograms to Age 50, Then Every Other Year
November 16, 2009
Cancer Society, others voice strong disapproval of federal recommendations. Women don't need to start having mammograms to screen for breast cancer until they're 50, and they only need to have those exams every other year, new government guidelines suggest.
Also, breast self-exams, which women have been urged to do routinely, have not helped lower the death rate from breast cancer, the guidelines add.
Not all agree with the revised recommendations, however.

Gene Linked to Breast Cancer Might Boost Heart Health
November 16, 2009
When BRCA1 is deactivated, it can lead to atherosclerosis, or hardening of the arteries, mouse study suggests. The over-activity of a gene known to boost a woman's risk for breast cancer may have a good side, making arteries healthier, a new study suggests.
The study, performed in mice, also found that when this gene, called BRCA1, is turned off, it promotes an inflammation that can lead to atherosclerosis or hardening of the arteries.
Although there has been no previous observation of increased cardiovascular death specifically in the large number of people who carry the BRCA1 mutation, there has been a surprising suggestion of higher non-cancer death in this population, noted study senior author Dr.

Gestures Processed in Brain's Language Center
November 14, 2009
Talking with your hands could be linked to evolution, research suggests. Words and gestures are processed in the same areas of the brain, a finding that may improve understanding of the evolution of language, researchers say.
In the study, MRI was used to monitor the brain activity of 20 volunteers as they watched video clips of a person either acting out gestures or voicing phrases that matched the gestures' meanings. Both the gestures and words triggered high levels of activity in the inferior frontal and posterior temporal areas, which are the language regions of the brain.

Chinese Scientists Develop Database on the Liver
November 13, 2009
Information on proteins could help guide treatments for hepatitis and more. Chinese scientists report that they have created an extensive database about proteins produced by genes in the human liver, an endeavor they say could become the foundation for new treatments for liver disease.
To develop the database, reportedly the largest of its kind for any organ, the researchers examined 10 liver-tissue samples from volunteers and identified 6,788 proteins, half of which had never before been encountered. One unexplained discovery, they said, was that many seem to be connected to diseases of the nervous system.

22 Million Sickened by Swine Flu in 6 Months
November 12, 2009
Revised estimation method gives clearer picture of pandemic, CDC says. At least 22 million Americans have come down with the H1N1 swine flu since the virus first surfaced in April and approximately 3,900 people have died, including an estimated 540 children, federal health officials reported Thursday.
While these numbers represent a significant jump in the numbers of sick, hospitalized and dead from previous figures, they don't mean that the swine flu has suddenly gotten worse. Instead, the new numbers are based on extrapolations from laboratory-confirmed cases of swine flu.
