Accessory breast

Accessory breast or supernumerary breast is a condition where an individual has more than the usual number of breasts. This condition is not uncommon and is present in both males and females. The additional breasts can occur anywhere along the milk line which extends from the upper arm to the groin.

Causes

The cause of accessory breasts is not fully understood. It is believed to be due to the incomplete regression of the milk line during embryonic development. This condition is often hereditary and can be passed down through generations.

Symptoms

Accessory breasts can vary greatly in size and shape. They can be as small as a mole or as large as a full-sized breast. The additional breasts may or may not have nipples and areola. They can also contain glandular tissue which can swell and become tender during menstruation or lactation.

Diagnosis

The diagnosis of accessory breasts is usually made by physical examination. However, imaging studies such as ultrasound or mammography may be needed to confirm the diagnosis and to rule out other conditions such as breast cancer.

Treatment

The treatment of accessory breasts depends on the symptoms and the individual's preference. If the accessory breasts are causing discomfort or are cosmetically undesirable, they can be removed surgically. However, if they are not causing any problems, no treatment is necessary.
