A number of studies have indicated that regular exercise may reduce the risk of breast, colon, and possibly prostate cancers.
Studies confirm that exercise significantly reduces the risk of both colon cancer (by up to 50%). Exercise also decreases the risk of breast cancer in pre and post menopausal women by up to 30%.
Low intensity exercise has a protective effect against colon cancer, according to studies, including the Nurses Health Study and the American Cancer Society’s Cancer Prevention Study II. People with colon cancer who exercise may reduce their risk of a recurrence.
Exercise also has a beneficial effect on people receiving treatment for cancer. Aerobic and resistance training can reduce fatigue in patients undergoing chemotherapy or radiation treatments for cancer. Fatigue is a common side effect of such treatments.
