Breast cancer is the malignant tumor (a tumor with the potential to invade other tissues or spread to other parts of the body) that starts in the cells of the breast. It occurs both in men and women. However male breast cancer is rare.

A woman’s breasts contain specialized glands that can produce milk. The breast structure consists of 15-20 lobes. Each lobe is made up of many smaller lobules which have groups of tiny glands that can produce milk. The milk travels through a network of tiny tubes (ducts) to a reservoir that lies just below the nipple. The dark round area of skin surrounding the nipple is called the areola. The breast also contains blood & lymph vessels and lymph nodes.
