STAY FIT

Estrogen increases as body fat increases—and that fuels certain kinds of breast cancer cells. The average reduction in risk for those who exercise a minimum of 150 minutes a week—only two and a half hours—is an estimated 12 percent. Shedding 5 to 10 percent of your body weight also slashes your breast cancer risk in half. Looks like there’s an incentive to signing up for that 8am CrossFit class.
