There is no optimal time for removal of paratits. It is recommended to perform the surgery 5~7 days after menstruation. The paratesticular breast is a congenital developmental abnormality due to the poor degeneration of breast tissue during the embryonic period. It can be divided into complete paratesticular breast and incomplete paratesticular breast, which is the extra breast appearing outside the normal breast, and can be diagnosed by ultrasonic examination. Like normal breasts, paratesticular breasts will be affected by the hormones secreted by the ovaries and change accordingly. They may be swollen and painful during the ovulation period or produce a small amount of milk during breastfeeding, but in general paratesticular breasts will not cause any adverse effects to the body. Most of them grow in front of or under the armpits. If there is hyperplasia or unexplained nodules, surgery should be performed in time to prevent malignant changes in a very small number of paratesticular breasts. Surgery is recommended to be performed 5-7 days after menstruation, when the ovarian hormone level is low, the size of the paratesticular breasts is relatively small, and the blood flow is not very rich, which is favorable for surgical operation, and it can reduce the bleeding during the operation. Postoperative dressing change can be given once every other day to avoid hematoma or effusion formation. When women have the presence of paratesticular breasts, they must go to the hospital in time to decide whether they need surgical treatment. Never take any unauthorized treatment to avoid delays and adverse outcomes.
