Overall, breast surgery is not major surgery. Breast surgery includes a variety of procedures, and lumpectomy biopsy and puncture biopsy are not major surgeries. Total mastectomy is slightly larger, but does not enter the abdominal and thoracic cavities and is superficial. Single mastectomy is now used, which preserves the large and small muscles of the chest and is not major surgery. Because screening tools can detect earlier cases, patients undergo localized segmental resection by breast-conserving surgery, which is very minor. For axillary lymph nodes, full axillary clearance used to be performed, but now the presence or absence of metastasis in the anterior axillary lymph nodes is evaluated by tracers, and those without metastasis can have their axillae preserved, which is not a major surgery and patients do not need to worry about it. The biggest problem of breast cancer surgery is the psychological stress of the patient and the risk of recurrence or metastasis. Through preoperative needle aspiration biopsy and general anesthesia surgery, such as breast and axillary conserving surgery, patients recover very quickly and can go down to the floor and resume eating and drinking the next day without much impact, and patients do not have to worry about surgical trauma.
