Exercise Can Lower Your Breast Cancer Risk

How Physical Activity Can Save Your Life

Is reducing your risk of breast cancer as easy as riding a bike? FITNESS tracked down one woman who knows -- Leslie Bernstein, PhD, former athlete, AFLAC chair in cancer research, and professor of preventive medicine at the Keck School of Medicine at the University of Southern California. She's the lead researcher on groundbreaking studies that show, definitively, that exercise is one great way to protect yourself from the disease. Her more than 20 years of research have found that women who walk, bike, or do any moderate workout regularly have about a 20 percent lower risk of breast cancer than those who don't. "Physical activity -- just 30 minutes a day -- is the easiest way to reduce your risk," says Bernstein.
