Can exercise reduce a woman's risk of breast cancer?

It may be the last day of National Breast Cancer Awareness Month, but the fight continues on year round -- and on one front, researchers are looking at whether or not exercise can reduce one's risk of a breast cancer diagnosis. There is some evidence to suggest that exercise not only reduces the chance of developing breast cancer, but that it may also help prevent a relapse of the disease in breast cancer survivors. A new study at the National Cancer Institute will break out of previous survey-based study methods and follow a set of inactive women between the ages of 18-35 as they encourage them to get active and measure the resulting effects. These women are either breast cancer survivors or at high risk for developing breast cancer, and must self-classify as sedentary to participate in the study. Once active in the study, the participants will be asked to walk 10,000 steps each day, and the effects on cancer relapse rate as well as effects on other cancer risk factors such as circulating hormone levels, cholesterol levels, and some immune markers will be determined.
