The recurrence rate for breast-conserving versus non-breast-conserving surgery is slightly higher than the five-year local recurrence rate of 2 to 3 percent for breast-conserving surgery and 1 percent for non-breast-conserving surgery. When performing a mastectomy for breast cancer, the surgeon will choose the appropriate surgical procedure based on the type and stage of the tumor. In the early stage, the breast-conserving method can be chosen for treatment. If the patient belongs to the advanced stage of breast cancer, he/she needs to treat the disease by total mastectomy. Patients who opt for breast-conserving surgery can still be treated with remedial total mastectomy and breast reconstruction if there is a recurrence in the affected breast. Localized recurrence after mastectomy usually manifests itself in the form of localized lumps, pain, and other symptoms, and is usually treated with excision of the recurrent focus and radiation therapy. When choosing mastectomy for breast cancer, patients should go to regular hospitals and choose the treatment suitable for their condition under the diagnosis of professional doctors.
