The five-year survival rate of stage III breast cancer with lymph node metastasis is around 50-60%, which is affected by various factors such as patient’s physical condition, tumor typing, and sensitivity to treatment, etc. The survival rate of stage III breast cancer with lymph node metastasis is around 50-60%. If the breast cancer has metastasized to the lymph nodes, it usually indicates that the disease is already in the middle or late stage, and the specific survival period needs to be considered according to the treatment effect, the underlying disease, the patient’s physical quality and other factors. It is recommended that patients cooperate with doctors to conduct a comprehensive examination and guide a good and reasonable treatment plan. In general, if the patient is younger, actively cooperates with the treatment, is more sensitive to the treatment, has better drug efficacy, and does not suffer from the underlying disease, the survival time will be relatively longer, possibly 5 years or more. If the patient is older, is not sensitive to treatment, the efficacy of the drugs may not be too good, and when there is a combination of hypertension, coronary artery disease and other underlying diseases, the survival time may be shorter. It may be under 5 years. Studies have found that the overall 5-year survival rate for stage III breast cancer is between 50% and 60%. Clinically, the survival rate can also be improved by surgical complete mastectomy with axillary lymph node dissection, along with treatments such as radiotherapy and targeting. Lymphatic metastasis of stage III breast cancer, it is recommended to go to regular hospitals for standardized treatment in time, so as not to delay the condition.
