The earlier oral cancer is found, the better the prognosis. Most people with early-stage cancers have an excellent cure rate. Even people with stage III or IV cancers who receive all suggested treatments, there is still a good chance of staying cancer-free for 5 years or longer.
Even after small cancers are cured, patients remain at risk of developing another cancer in their mouth, head, or neck. That's why follow-up exams are crucial.
