Study: Exercise can help reduce breast cancer risk


NEW HAVEN, Conn. (WTNH)–Experts believe there is a link between working out and reduced risk of getting breast cancer.

French researchers looked at nearly 60,000 women, comparing physical activity levels and whether or not they received breast cancer diagnoses. They found that those who exercised regularly for the past four years had a 10 percent lower risk of breast cancer.

Even modest exercise–meaning three to six hours of biking or slow walking per week–seemed to provide a benefit. But what about those who only used to exercise?

Women who had been active only five to nine years before menopause did not see the same benefits. Of course, the study can’t tell us for sure that exercising causes breast cancer risk to go down. Perhaps women who exercise also do other things that help them.

But it does suggest that staying active may cut your risk. So why not take matters into your own hands?

It could literally be as easy as a walk in the park.

Researchers also found that regular physical activity cuts the odds of breast cancer is postmenopausal women, but that the protection disappears if they stop exercising.
