"E! News" host Giuliana Rancic announced Monday on NBC's Today show that she has breast cancer, and that she was alerted to the cancer via a mammogram during her third in vitro fertilization attempt… Breast cancer is the second most common cancer in women (after skin cancer), and while it's far more common in women, it can also develop in men. There are several different types of breast cancer, though ductal carcinoma (cancer that starts in the milk ducts of the breast) is the most common, according to the Mayo Clinic.
