Breast

Breasts are the female organs on the front of the chest, consisting of the nipple, areola, and breast tissue. Breasts are related to breastfeeding (fertility) and sexual activity. Breast symptoms include breast pain, breast redness, breast lump, breast swelling, nipple symptoms, and many other breast symptoms. Breast conditions include mastitis (breast infection), breast abscess, fibrocystic breasts, breast cancer, and many other breast disorders.

Breast basics

A woman’s breast is made of glandular tissue, connective tissue, fatty tissue, blood vessels, lymph tissue, and nerves. Each breast contains up to 20 sections of glandular tissue called lobes. Each lobe has many smaller sections called lobules, where milk is made. Milk flows from the lobules through thin tubes called ducts to the nipple. The nipple is the small, raised area at the tip of the breast. The areola is the area of darker-colored skin around the nipple.

Each breast also contains lymph vessels. These are thin tubes that carry lymph to small, bean-shaped glands called lymph nodes. Lymph nodes are found near the breast, under the arm, and throughout the body. Lymph nodes and lymph vessels are part of the lymph system, which helps your body fight disease and infection. The chest muscle and chest wall are behind the breasts.

Anatomical Information about Breast

The Breasts

Inside a woman's breast are 15 to 20 sections called lobes. Each lobe contains many smaller sections called lobules. These are groups of tiny glands that make breast milk. Breast milk flows through thin tubes called ducts to the nipple. Fat and other tissue fills the spaces between the lobules and ducts. The breasts also contain lymph vessels, which are connected to small, round masses of tissue called lymph nodes. Lymph nodes produce cells that help the body fight infection. Groups of lymph nodes are near the breast in the underarm, above the collarbone, and in the chest behind the breastbone.
