Breast cancer generally starts in the inner lining of the milk ducts (tubes that carry milk to the nipple) or lobules (glands that make milk) in the breast. It occurs not only to females, but males may also get affected, although male breast cancer is very rare. In fact it is 100 times more frequent among women than men, but the survival rates are same for men and women.

The American Cancer Society says that physician detects breast cancer by mammogram, a lump that is found in lymph nodes in the ampits.
Other symptoms of breast cancer are changes in breast size, dimpling of skin, nipple inversion, or spontaneous single-nipple discharge.
