Breast cancer is cancer that forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare.
My Electronic MD is a symptom checker which allows you to find likely causes of your symptoms in a relatively short period of time. After selecting your main complaint, you will be asked to select a scenario representing a constellation of symptoms that best fits your history, similar to the way physicians make diagnoses in the office.
