A tremendous amount of promising research is under way to determine the cause of breast cancer and to establish effective ways to prevent it. Still, doctors can't always explain why one woman develops breast cancer and another doesn't.
Male breast cancer is rare. It happens most often to men between the ages of 60 and 70. Risk factors for male breast cancer include exposure to radiation, a family history of breast cancer and having high estrogen levels, which can occur with diseases like cirrhosis or klinefelters syndrome.
Symptoms of male breast cancer include lumps, changes to the nipple or breast skin, or discharge of fluid from the nipple. Treatment for male breast cancer is usually a mastectomy, which is surgery to remove the breast. Other treatments include radiation, chemotherapy and/or hormone therapy.
