What is accessory breast

Axillary accessory breasts refer to the extra breasts that appear in addition to the normal pair of breasts on the body. They are usually located in front of the armpits or under the armpits, or on the left and right of the normal breasts on the chest, abdomen, groin, etc. The reason for the formation of axillary accessory breasts is that humans have 6 to 8 pairs of mammary glands in the two lines from the armpit to the groin during the test tube embryo stage. Before birth, except for the pair on the chest that are preserved again, the others have atrophied. Let’s discuss the detailed introduction of what underarm accessory breast is below.

Clinical symptoms

Generally, the size of the accessory breast under the armpit varies from person to person. Most people do not have any special feeling. Some patients have swelling and pain before the menarche, and the swelling and pain disappear after the menstruation.

Most cases present with swelling or protrusions in front of or under the armpits, and may also involve fully developed nipples. You can feel a hard lump in the accessory breast under the armpit, which is the growing and developing mammary gland. It can also occur on the left and right sides of the normal breast, in the abdomen, groin, inner thigh, etc. Some can develop into breasts that are very different in shape from normal breasts and include nipples.

The changes in the size of the accessory breast under the armpit are more obvious during pregnancy and lactation. Generally, during pregnancy and breastfeeding, the accessory breasts under the arms will significantly enlarge and even produce milk. After breastfeeding, the armpit accessory breasts do not shrink, so the main symptoms are more obvious.

Axillary accessory breasts affect your appearance, dressing style and business activities. The vast majority of patients seek medical treatment for a desired appearance improvement. The accessory breasts under the armpits contain breast tissue and therefore carry the risk of breast cancer.
