The survival time of oral cancer patients is directly related to the treatment and patients’ own conditions. Generally speaking, if early oral cancer receives regular treatment, the five-year survival rate is about 55%. If the oral cancer is in middle or late stage and metastasis has occurred, the survival period will be shortened accordingly. 1. Early oral cancer: Early oral cancer can be treated with radical surgery and postoperative radiotherapy, which has better clinical effect and prolongs the life of patients significantly, and the survival rate of patients with 5-year survival period is about 55%. 2. Intermediate and advanced oral cancer: If intermediate and advanced oral cancer with distant metastasis has occurred and cannot be treated by radical surgery, and can only be treated by conservative treatment, then the life span of patients will be affected. How long an oral cancer patient can live is related to the severity of the disease and the patient’s personal physique. The earlier the treatment is given, the lower the chances of recurrence as well as distant metastasis, and the higher the chances of recovery. Moreover, after surgery, patients need to actively cooperate with doctors in treatment, which can also prolong the life cycle to a certain extent.
