Exercise Helps Prevent Breast Cancer

Exercise may help prevent breast cancer, and help those who do get it cope, two new studies show.

The first study, based on interviews with 15,000 women, shows that women who get more than six hours of strenuous exercise a week, and have no family history of breast cancer, may be 23% less likely to develop the disease than women who don't exercise at all.

The second study shows a 12-week group exercise program may boost mood and physical function in women with early-stage breast cancer.

The researchers don't promise exercise will prevent breast cancer, or blame breast cancer on a lack of exercise. Many factors affect cancer risk.

But, they do report exercise appeared to have benefits in protecting against cancer for women of all ages.
