Healthy Weight, Diet, and Ovarian Cancer Survival

Ovarian cancer is among the most deadly women’s cancers. That’s because its symptoms, such as abdominal bloating, are difficult to diagnose until it has progressed to a late stage. Only 44 percent of ovarian cancer survivors live 5 years past diagnosis.

Unveiling #1 - Covered & ConfidentBut results of a new study of post-menopausal women in the Women’s Health Initiative trial unveiled this week at our research conference associate higher diet quality index score in combination with physical activity with greater survival after diagnosis of ovarian cancer. Researchers at the University of Arizona Cancer Center presented these results in a poster at our conference.

The results are not yet published and has not yet gone through the peer-reviewed process.

Study author Tracy Crane, MS, RD, said of the ┬ástudy, “This secondary analysis supports the ongoing LIVES study, the largest-ever randomized controlled trial (RTC) to investigate the effects of diet, weight and physical activity on ovarian cancer survival.”

Talking About… Processed Meat and Cancer

meat delicaciesDiets high in red and processed meats are a cause of colorectal cancer. Period.

That finding from our 2007 expert report was only strengthened in the 2010 Continuous Update Project Report on Colorectal Cancer, which reviewed evidence published since the 2007 report.

At this writing, more studies continue to be added to the CUP database; in 2017, the CUP expert panel will review the collected evidence once again and issue updated Recommendations for Cancer Prevention.

The existence of a link between red and processed meat and colorectal cancer is no longer surprising. But now researchers are asking the next questions –1. What is it, exactly, in red and processed meat that’s responsible for the increased risk, and 2. Is there anything we can do about it?

Amanda J. Cross, PhD, of Imperial College London, UK, will be presenting evidence tomorrow at our 2013 AICR Research Conference on Food, Nutrition, Physical Activity and Cancer. Continue reading


Keep Moving All Day for Lower Cancer Risk

It’s possible to do regular exercise and still be a couch potato. And that inactivity can increase your cancer risk, said Charles E. Matthews, Ph.D., at today’s AICR conference session on Sedentary Behavior and Physical Activity. Matthews and other researchers are finding that sitting (being sedentary) too much is a separate health risk that needs to be studied separately from the health-protective effects of exercising.

“You can exercise 30 minutes a day, but if you sit the rest of the time your overall activity level is not that high,” he says. And it’s the total time you spending sitting that may be associated with cancer, according to Dr. Matthews (right), Physical Activity Epidemiologist and Investigator in the National Cancer Institute’s Division of Cancer Epidemiology and Genetics in Bethesda, Maryland.

Many adults spend 70 percent or more of their waking hours sitting — at desk jobs, in front of ┬átelevision and computer screens and in the car. On top of this inactivity, eating too much high-calorie convenience food has led to the obesity epidemic in this country, he says.

Too much sitting may be associated with an increased risk of cancer in several ways, according to Dr. Matthews and Neville Owen, PhD, a prominent inactivity researcher at Baker IDI Hart and Diabetes Institute in Australia. When a person sits too much, the mitochondria in our muscle cells don’t do their jobs, and as a result our energy metabolism it lower, increasing risk for weight gain.
