In this best of series interview, Susan Wadia-Ells, Ph.D., discusses breast cancer as an unnecessary U.S. epidemic and how to prevent it, which is the topic of her book, “Busting Breast Cancer: Five Simple Steps to Keep Breast Cancer Out of Your Body.” This year alone, an expected 300,000 women in the U.S. will be diagnosed with invasive breast cancer. Another 50,000 are projected to be diagnosed with non-invasive breast cancer, which in all likelihood isn't cancer at all.
