The female breast has milk glands and ducts that are wrapped by a layer of fat. Each breast consist of 12 to 15 glands where milk is produced. Milk is collected in the ducts that drain via the nipples.

The breasts are affected by the female hormone during the reproductive phase. As a woman ages, the milk glands and ducts will shrink and replaced by fatty tissues. Breast cancer usually develop within these glands and ducts.
