Supernumerary breasts, also known as polymastia, is a rare condition in which a person has an extra breast or breasts. These extra breasts may be located anywhere on the body, but are most commonly found on the chest, near the normal breasts. They may be fully developed, or may only be small mounds of tissue.

The most common symptom of supernumerary breasts is the presence of extra breast tissue, which may appear as an extra nipple or a small mound of breast tissue. Other symptoms may include pain, tenderness, and swelling in the area of the extra breast tissue. In some cases, the extra breast tissue may produce milk.

The exact cause of supernumerary breasts is unknown, but it is believed to be related to a combination of genetic and environmental factors. It is thought that hormones, such as estrogen, may play a role in the development of extra breasts. Other possible causes include certain medications, obesity, and certain medical conditions.

The treatment for supernumerary breasts depends on the size and location of the extra breast tissue. In some cases, no treatment is necessary. However, if the extra breast tissue is causing physical or emotional discomfort, it can be surgically removed. Other treatments may include hormone therapy, laser therapy, or liposuction.
