Prognosis of lip cancer is quite good, with a five year survival rate at 95% -100% for lower lip carcinoma and 58% for upper lip carcinoma. Intraoral cancer prognosis is dependent upon the stage of lymph node involvement. If no metastases have occurred, the five-year survival rate is 83%, decreasing to 41% with cervical node involvement and 9% when nodes below the clavicle are involved.
