The survival time of patients after breast malignant tumor surgery is based on the severity of malignant tumor, whether or not standardized chemotherapy is given after surgery, and different factors of patients’ personal constitution, as follows: 1. Long-term survival: If patients’ breast malignant tumor belongs to early stage and does not cause more lymph nodes and invasion of surrounding organ tissues, patients’ own recovery ability is stronger, and patients actively undergo chemotherapy treatment, targeted therapy, endocrine therapy and other comprehensive treatments after surgery. If the patient’s breast malignant tumor is in early stage and has not caused many lymph nodes and invasion of surrounding organs and tissues, the patient’s own recovery ability is relatively strong, and after surgery the patient actively carries out chemotherapy treatment, targeted therapy, endocrine therapy and other comprehensive treatment, the survival time of most patients in five years after surgery can be more than 80%, and the survival time of some patients can even reach about 20-30 years. 2. Patients are older and their recovery ability is poorer, patients have a shorter survival time, some of them only have about one year of survival time.
