The five-year survival rate of breast cancer is simply understood as the clinical cure rate, that is, if a patient with breast cancer survives for more than five years after treatment, the breast can be considered to be cured. In clinical practice, for malignant tumors, the survival period is mainly represented by the five-year survival rate to show the effectiveness of its cure. Five-year survival rate means that the patient can survive for more than five years after comprehensive treatment. Generally speaking, whether it is breast cancer, thyroid cancer, stomach cancer, intestinal cancer or liver cancer, after symptomatic treatment or surgery, if the patient can survive for more than five years without recurrence or metastasis, it is usually understood to have been cured. Therefore, the five-year survival rate of breast cancer also means the clinical cure rate, that is, the patient has been cured of breast cancer through comprehensive treatment.
