1. If you are Postmenopausal, to Prevent Breast Cancer
    Studies show that “Women who are overweight or obese after menopause have a 30 to 60 percent higher breast cancer risk than those who are lean.” This is not to say that any woman who is overweight after menopause will get breast cancer, or on the flip side, that any woman who is lean will not. But anything that has the ability to increase your risk as significantly as 60 percent needs to be addressed. And the first step is to know your BMI so you can act accordingly to protect yourself.
