In general, the recovery time of the wounds caused by mastectomy is fast and can heal within a week if no infection occurs, but the exact healing time depends on the purpose of the puncture. The size of the wound and the healing time vary depending on the purpose of the puncture. If a breast nodule is found and the puncture is performed to clarify the nature of the nodule, the incision is small and heals quickly and can heal within a week if no infection occurs. In some patients, mastitis forms an abscess and requires puncture and drainage, and the wound formed by the puncture will not heal until the pus is completely drained. Local care of the wound after mammary puncture is crucial. Keep the area clean, change the gauze regularly, observe the healing of the wound when changing the gauze, and seek medical attention if redness, swelling, pain or hard nodes appear.
