Exercise Helps African American Women Reduce Breast Cancer Risk
African American women who play basketball, swim, run, do aerobics, or walk briskly for five or more hours per week may reduce their risk of breast cancer, researchers say. The findings come from a study of more than 44,000 African American women ages 30 and older who were followed for 16 years. Women who exercised vigorously five to six times per week had an 11 percent lower risk of breast cancer than those who clocked in less than an hour’s worth of exercise weekly. Exercising for seven or more hours a week led to a 26 percent lower risk of developing the disease. The walking had to be brisk, though. There was no breast cancer benefit for women who merely strolled.
