The 5-year survival rate is often an indicator to reflect the survival time of malignant tumor patients. The 5-year survival rate is how many patients can live to 5 years or even longer if they have this type of malignant tumor. Even for the same tumor, the 5-year survival rate is different for different clinical stages. The earlier the stage is, the higher the 5-year survival rate will be. If the tumor does not recur or metastasize 5 years after surgery, the chance of recurrence and metastasis in the future is very small, and the 5-year survival rate can be considered as the cure rate of the tumor.
