Patients with breast tumors undergoing surgical treatment are often left with partial or total loss of breast, which causes great trauma to the patient’s body and mind. For example, modified radical mastectomy for breast cancer, skin-preserving mastectomy, and partial or even total removal of breast for benign breast tumor patients, these troubles can be solved by breast reconstruction. Generally speaking, breast reconstruction does not require strict age requirements and can be performed as long as the health condition allows. “Breast reconstruction surgery is divided into immediate reconstruction and delayed reconstruction, also known as stage I reconstruction and stage II reconstruction. First-stage reconstruction is the reconstruction of the breast immediately after radical breast cancer surgery, which is performed at the same time as the surgical treatment. This way there will be no experience of missing breast and there will be no mental depression caused by the physical defect. Delayed reconstruction, on the other hand, is performed some time after radical breast cancer surgery. After the patient has experienced the pain of breast loss, she is fully prepared and needs reconstruction, and reconstruction can not only restore the beauty of women’s body curves, but also repair the sense of loss in women’s mind. In terms of aesthetic results, one-stage reconstruction is more satisfying. Therefore, for breast surgeons, it is more recommended to do one-stage reconstruction. Therefore, before surgery for breast tumors, especially breast cancer, it is important to determine the surgical method and not to miss the time if it is suitable for one-stage reconstruction. Depending on the materials used for breast reconstruction, there are two types of breast reconstruction methods: autologous flap reconstruction and prosthesis reconstruction. Both methods have their own advantages and disadvantages and indications, and the surgeon will communicate with the patient before surgery about the most suitable option for the patient’s specific condition. In addition, even with one-stage breast reconstruction, many patients may undergo more than 2 surgeries to obtain the best appearance. For example, some patients who require radiation therapy may start with an expander and have a second surgery to replace the permanent prosthesis; and some patients who have had their nipples and areolas removed may have a second surgery to reconstruct the nipple and areola.
