How long is the survival period after total excision of intermediate stage breast cancer cannot be generalized, and the 5-year survival rate after surgery can reach about 60%. Intermediate stage breast cancer means that the tumor is relatively small with axillary lymph node metastasis, or the tumor is relatively large without axillary lymph node metastasis, which belongs to intermediate stage breast cancer. Generally, after active treatment, the prognosis is good, but the specific survival period varies from person to person, and the 5-year survival rate after surgery can reach about 60%. The preoperative examination should be strengthened in the middle stage of breast cancer, and if there is no contraindication to surgery, modified radical surgery, i.e. total excision, is feasible. After surgical excision, chemotherapy, radiotherapy, targeted therapy and other comprehensive treatments should be guided according to the examination results, which can help patients to improve the clinical cure rate, prolong the survival time as much as possible and improve the quality of life. After mid-stage total excision of breast cancer, postoperative checkups should also be conducted regularly as prescribed by the doctor, and close attention should be paid to the recovery of the condition.
