A woman has a one in eight chance of getting breast cancer during her lifetime. While not as common, men also can get breast cancer.

Breast cancer cells often form a tumor that either can be felt as a lump or seen during a mammogram. Common types of breast cancer include the following:

  • Ductal carcinoma in situ
  • Invasive carcinoma

Most types of breast cancer start in tubes called ducts that carry milk to the nipple, while others begin in glands that make breast milk.
