What causes accessory breasts?

Women all hope that their breasts are tall, firm and full, but some women, although their breasts are full, are very embarrassed by the accessory breasts under their arms, especially in the summer when clothes are thin. The accessory breasts under their arms will be accidentally exposed, making the women's figure look unattractive. How do accessory breasts under their arms come about? What are the causes of underarm accessory breast? Let’s take a detailed look at it below.

1. The recession is not complete

In the sixth week of human embryonic development, the ectoderm cells on both sides of the ventral surface of the human body thicken to form ridges, which are equivalent to the arc-shaped connecting line from the armpit to the groin. These two ridges are called the lactogenic line, and there are many mammary gland rudiments on the surface. Under normal circumstances, when the embryo develops to the ninth week, except for the mammary gland rudiments in the chest that continue to grow, everything else gradually declines and disappears. Some women will have accessory breast under the arms, which is mainly caused by the failure of the mammary gland to atrophy or incomplete atrophy. This type of accessory breast under the arms is generally called congenital accessory breast under the arms. Congenital accessory breast under the arms is further divided into complete accessory breast under the arms and incomplete accessory breast under the arms. Complete accessory breast under the arms is the same as normal breast, with complete mammary tissue, nipples, and nipples. Moreover, this type of accessory breast under the arms will cause pain with the arrival of menstruation, and will continue to secrete milk with the arrival of pregnancy. Incomplete axillary accessory breasts have no breast tissue and may have nipples or nipples. It is not easy for milk secretion to occur due to the arrival of pregnancy.

2. Influence of external forces

In addition, the main reason for some women to have accessory breasts under the arms is due to external forces. Wearing tight underwear for a long time and compressing the chest for a long time will push the flesh that originally belonged to the chest outwards, thus forming accessory breasts under the arms.

3. Obesity

If a woman is too fat, fat will accumulate under the armpits to form underarm breasts.

That’s all we have to say about the three causes of axillary accessory breast. Generally speaking, if the acquired axillary accessory breast has no mammary tubes or nipple tissue and is not accompanied by pain, it usually does not require surgical removal. If it is congenital axillary accessory breast, it is recommended to go to the hospital for a physical examination as soon as possible, let the doctor classify and diagnose your axillary accessory breast, and choose the appropriate treatment method for treatment in a targeted manner.
