Exercise, Even Mild Physical Activity, May Reduce Breast Cancer Risk, University of North Carolina Study

A new analysis has found that physical activity – either mild or intense and before or after menopause – may reduce breast cancer risk, but substantial weight gain may negate these benefits. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings indicate that women can reduce their breast cancer risk by exercising and maintaining their weight. While studies have shown that physical activity reduces breast cancer risk, many questions remain. For example, how often, how long, and how intense does physical activity have to be to provide benefits? Also, do women with all body types experience a reduced risk when they exercise, and does exercise reduce the risk of all types of breast cancer?
