Structure of the breast


Structure of the breast


After a woman has a baby, glands in the breast produce and release milk.

These milk-producing glands are called lobules. The tubes that connect them to the nipple are called ducts.

Besides lobules and ducts, the breast is also made up of fatty, connective and lymphatic tissue.

A lump in your breast is not necessarily cancer. A variety of benign conditions can also cause a lump in your breast.
