(Newser) – Women who walk at least one hour a day can lower their risk of breast cancer, according to a new study from the American Cancer Society. Over 17 years, researchers monitored the physical activity of more than 70,000 postmenopausal women. Those who walked at least seven hours a week—even if it were their only form of exercise—had a 14% lower risk. Women who engaged in more vigorous activity lowered their risk even more—they were 25% less likely to get breast cancer.
