It is not possible to generalize how long a patient can live if the breast cancer has spread to the lymph nodes in the armpit. Breast cancer spreading to axillary lymph nodes may be in stage II or stage III. Clinically, “5-year survival rate” is often used to roughly assess the survival time of patients, according to statistics, the 5-year survival rate of patients with stage II breast cancer is 80%-90%, and the 5-year survival rate of patients with stage III breast cancer is 40%-70%. The survival time of breast cancer spreading to axillary lymph is not generalized, the specific survival time is related to clinical stage, pathological type, treatment method, physical condition and other factors, according to statistics, the 5-year survival rate of patients with stage II breast cancer is 80%-90%, and the 5-year survival rate of patients with stage III breast cancer is 40%-70%. It should be noted that breast cancer patients can improve the healing process and reduce the adverse effects of the disease through early detection, early diagnosis and early treatment. It is recommended that patients actively undergo regular treatment as soon as possible, and in general, the earlier the disease is detected, diagnosed and treated, the smaller the impact of the disease on the life expectancy, and it is recommended that patients seek medical treatment in a timely manner.
