Nasopharyngeal cancer can be categorized into four stages, at present, there is no relevant authoritative information stating how long can one live in stage III nasopharyngeal cancer. Generally speaking, the 5-year survival rate of stage III nasopharyngeal cancer is about 68%. Clinically, “5-year survival rate” is often used to roughly assess the survival of tumor patients, but it does not represent the specific survival period of individuals. The specific survival period of patients with nasopharyngeal cancer stage III mainly depends on clinical stage, physical quality, pathological type, treatment method and other factors, so it cannot be generalized and there are obvious individual differences. According to statistics, the 5-year survival rate of nasopharyngeal cancer stage I is about 95%, stage II is about 85% and stage IV is about 50%, therefore, the earlier the clinical stage, the higher the survival rate. All in all, nasopharyngeal cancer patients need to go to the hospital for treatment in time, strengthen daily life management, and have follow-up examinations on time.
