In general, patients can live a long time after mastectomy. In general, the overall cure rate of breast cancer is high, especially in early stage breast cancer, and patients may survive for five years or even more than 10 years. In addition, it is recommended that after surgery, patients should decide the subsequent treatment, including endocrine therapy, chemotherapy, targeted therapy, etc., based on the pathological results or molecular typing results, and that they should come to the hospital for regular review, usually for life. Overall, the survival time of patients is relatively long. If signs of tumor recurrence or metastasis are found during the review process, timely treatment is needed.
