Study: Every decade of being overweight ups cancer risk for women

AICR’s evidence shows that carrying extra body fat increases risk for 11 types of cancer, including postmenopausal breast and endometrial. Now a new study looking at how long women have overweight and obesity suggests that if women keep their weight steady and/or lose weight – even small amounts – that may help lower risk for several cancers, especially postmenopausal breast and endometrial.

The study gives more insight into whether losing weight leads to lower cancer risk. It makes sense that it would, and we know it helps prevent other chronic conditions like type 2 diabetes, but researchers are still working to establish the link with cancer risk.

    Study: Lose weight through diet alone, or with exercise, cut cancer- promoting substances

    AICR’s evidence shows that having too much body fat increases risk for eleven cancers. But researchers are looking at whether losing weight, once overweight, would lead to lower risk for these cancers. Now a new study from researchers at Fred Hutchinson Cancer Research Center shows how weight loss – through diet alone or diet and exercise – might change pro-cancer substances in the body.
    The 12-month controlled trial of 439 healthy, postmenopausal women with overweight/obesity included 4 randomized groups: calorie restriction diet; moderate activity (goal of 3.75 hours per week), diet and exercise, and no intervention. Researchers wanted to see if these lifestyle changes would affect four substances in the body (biomarkers) that influence formation of blood vessels needed for tumor growth. Fat cell growth also requires a greater blood supply, so these biomarkers are also associated with increasing fat tissue.

    After 12 months, women in the exercise group lost 2.4% of their body weight; diet only reduced by 8.5% and those exercising and dieting lost 10.8% of their weight. And the more they lost, the more their biomarkers were reduced. Read more… “Study: Lose weight through diet alone, or with exercise, cut cancer- promoting substances”

      Can Pasta Help with a healthy weight – and cancer prevention?

      The most recent Dietary Guidelines for Americans recommend the Mediterranean Diet as one way to eat healthfully. Yet pasta, a common food in this diet, is often seen as packing on the pounds. So scientists in Italy wanted to see if they could tease apart how pasta, as part of the Mediterranean diet, may affect a person’s weight and body shape.

      That’s important for cancer risk, because understanding how the food you and your family eat every day affects weight is one important key to lower risk. AICR’s evidence shows that having too much body fat links to higher risk for eleven types of cancer, including colorectal, liver and postmenopausal breast.

      In this study, researchers used data from two large studies in Italy to see if  people’s pasta eating linked to their weight and waist size. Read more… “Can Pasta Help with a healthy weight – and cancer prevention?”
