First of all, among many malignant tumors in the human body, the treatment of breast cancer is relatively very standardized and the prognosis is very good, with the overall 5-year survival rate reaching about 80%. If the tumor is very early, the overall 5-year survival rate can reach about 80% for patients with stage I breast cancer. For advanced breast cancer patients, if they can be actively treated, including chemotherapy, radiotherapy, endocrine therapy and targeted therapy, etc., some reports show that the 5-year survival can reach about 40%-50%. However, this is a statistical concept, and the effect is not the same for each individual. Some people may have a recurrence 1-2 years after the surgery, while others may even live longer. Therefore, when breast cancer is detected, it is important to adopt standardized treatment, including surgery and radiotherapy after surgery, as well as regular follow-ups in the hospital, because if metastasis or recurrence is detected at an early stage during follow-ups, there are still ways to treat the disease.
