The 5-year survival rate of breast cancer after metastasis to lymph nodes is above 80%, statistically 5-year survival rate, but it does not mean that the patient can only live up to 5 years, only that the probability of recurrence and metastasis after 5 years is very high. If there is no recurrence and metastasis after 5 years, it means that the patient can continue to survive for a long time, and the longer the survival time, the lower the probability of recurrence and metastasis of the tumor. When breast cancer has axillary lymph node metastasis, it is usually necessary to undergo modified radical surgery for breast cancer, that is, to remove the breast, and then the axillary lymph nodes need to be cleared. After the surgery, according to the type of pathology, the next treatment plan will be decided, whether chemotherapy or chemotherapy and targeted therapy are needed for treatment, and regular follow-up and review are needed.
