The survival time of breast cancer patients with metastasis to lymph nodes needs to be determined according to the lymphatic metastasis, pathological type and treatment. Breast cancer metastasis to lymph nodes is usually in the middle and late stage, and requires active treatment such as surgery and radiotherapy to prolong the survival time and improve the quality of life. If the patient has good pathology and the number of lymph nodes involved in lymphatic metastasis is relatively small, the 5-year survival rate is relatively high, about 80%, after complete clearance during surgery. Patients with a poorer pathological type and a higher number of lymph nodes involved in lymphatic metastases or who have started to invade distant organs have a relatively low 5-year survival rate and a poorer prognosis. Post-surgical radiotherapy, targeted therapy or Chinese medicine treatment also have an impact on the survival time of patients, and patients need to actively cooperate after surgery. Overall, the prognosis of breast cancer is better than other malignant tumors, and patients need to build up confidence and actively cooperate with the treatment.
