Underarm paratits do not need to be removed. Associate breasts are mainly formed during congenital development and do not completely subside before birth, manifesting in the appearance of associate breasts in the armpits. There is also normal breast tissue inside the paratesticular breast. If there is no pain and it does not affect the aesthetics, it may not need to be removed. However, it is important to come to the hospital for frequent checkups and follow-ups, as the internal breast tissue may also become diseased. If the secondary breast grows large and affects the aesthetics, or if there is pain inside the secondary breast, i.e., if there is cyclic pain to consider breast hyperplasia, the secondary breast needs to be removed. Removal of the paratesticular breasts can be done using minimally invasive methods, with smaller wounds on the skin, and after the surgery, the scars as well as the incisions are more aesthetically pleasing. Traditional excision of the paratesticular breasts can also be used, with the advantage of a more complete removal and the disadvantage of possible scarring.
