A recent review article in the journal Cancer found that one of the most important ways to reduce risk of breast cancer is to avoid gaining weight. That means balancing a healthy diet with plenty of exercise. Research also suggests that if you’re overweight, losing those extra pounds before age 45 can reduce your risk of breast cancer after menopause. Even if you’re past your forties, managing your weight through physical activity helps. A study of over 100,000 women reported that those who got regular, strenuous exercise had a lower risk of developing breast cancer than others who didn’t. Exercise may help lower levels of hormones that are involved in breast cancer. Commit to regular exercise, if you haven’t already.
