The presence or absence of nipple after breast reconstruction depends firstly on whether the nipple and areola are preserved after mastectomy. For example, if some lumps are far away from the nipple and areola, after surgical resection of the mammary gland and removal of the subcutaneous glands, the pathological examination suggests that the nipple and areola are not involved by the tumor, and the patient will definitely have nipple and areola after breast reconstruction with prosthesis or autologous tissue in this case; in some cases, the lumps of the patients are close to the nipple and areola, and after surgical resection of the mammary gland, it is found that the nipple and areola are affected, and the nipple and areola are cut off, Some patients will have the nipple and areola cut off after the surgical excision of the breast and find that the nipple and areola are involved, because the surgical principle of surgical oncology is to ensure that the local excision is clean as much as possible, and if there are residuals in the local area, it will increase the recurrence rate of the local area. For patients without nipple and areola, there are ways to deal with them, such as using local skin for nipple reconstruction, and then using tattoos to color the nipple and areola to achieve certain results.
