Surely, everyone can benefit in some way from yoga. Women with breast cancer that has spread beyond the breast, however, may benefit greatly from a tailored program featuring gentle yoga postures, breathing exercises, and meditation.

The great benefits: less pain and fatigue and more vigor, relaxation, and acceptance," says Dr. James W. Carson from Duke University Medical Center and lead of a study published in the Journal of Pain and Symptom Management.

Carson says women with advanced breast cancer need effective methods for curbing cancer-related symptoms.

The pilot study included 13 women who attended yoga classes once per week for eight weeks. The women, with an average age of 59 and with diagnoses occurring an average of seven years earlier, were helped significantly. They felt more invigorated and gained a greater sense of acceptance. They also found they felt better not only on the day they practiced yoga but the next day too.

This study offers the first, small-scale evidence for yoga's potential benefits for women with limited life expectancy.

Lung and colorectal cancer drug Avastin has been tested for the first time against the most common and deadly form of brain cancer.

Duke University researchers used Avastin, known chemically as bevacizumab, in combination with a standard chemotherapy agent in patients with recurrent brain tumors called gliomas. Good news -- the two drugs together stopped tumor growth for twice as long as any other therapy.

Gliomas are mostly incurable in all cases, but this new treatment approach may extend life and may help preserve physical and mental function for a longer period of time for patients fighting this deadly disease.

"These results are exciting because of the possible implications for a patient population that currently has the poorest possible prognosis going into treatment -- those with malignant brain tumors that have recurred after initial treatment," says the lead researcher whose findings appear in the journal Clinical Cancer Research.

When she asked her teenage daughters whether or not she should accept the American Cancer Society's Mother of the Year award, the response was a resounding, "Mom, of course." So Sarah Ferguson, the Duchess of York, accepted the anti-cancer honor this week and told ABC's George Stephanopolous on Sunday why she is a good mom and a healthy role model.

"They see that I go running, I get on my bicycle, I do yoga, pilates, whatever else I do," Ferguson said. "Do you know what they do? Get up off the sofa, turn the television off, walk to work, walk around the block, more vegetables, more fruits at school, less soda pops, less fast food."

Ferguson, 47, says cancer prevention starts with good role modeling -- which is exactly what she has done as mom to princesses Beatrice and Eugenie.

"I can safely say one of the best things I've done is be a good mother," Ferguson said.

Ferguson, author of memoir My Story and spokeswoman for Weight Watchers, first became known as the wife of Britain's Prince Andrew, the Duke of York. The pair divorced in 1996, but Ferguson's positive public persona has remained untarnished.

Eleven is the magic number.

Eleven pounds of lost weight can reduce the risk of an advanced form of prostate cancer, according to researchers from the American Cancer Society and the Duke University Prostate Center.

Researchers, who tracked the weight of 70,000 men between 1982 and 1992 and then followed them until 2003, found men who lost more than 11 pounds had a lower risk of developing prostate cancer than men whose weight remained the same.

Studies have long shown obese men are at greater risk for prostate cancer. But this study, published in this month's Cancer Epidemiology, Biomarkers & Prevention, is the first to indicate that recent weight loss can decrease risk by roughly 40 percent.
