Survival rate is also known as the clinical survival rate, which is usually five years. However, the 5-year survival rate is only an estimate, and the specific survival period needs to be considered in conjunction with many factors, such as the histological type of the tumor, the hormone receptor status, the metastatic spread of the tumor, the treatment plan and the treatment effect, as well as the patient’s own physical condition and psychological quality. Patients with stage IV breast cancer may have multiple metastases, such as lung metastases and bone metastases, which may not be curable by surgery, but can be considered through chemotherapy, targeted therapy, endocrine therapy and other comprehensive treatments to improve the survival rate and prolong the survival of patients.
