American Dental Association PSA - Oral Cancer "It's been said that nobody ever dies from dental disease, but they do from oral cancer. Oral cancer afflicts 36,000 people every year. Only one in three victims lives longer than five years after treatment, often because the cancer is discovered too late. Know the signs and protect yourself. Watch for these oral symptoms of possible malignancy, a swelling or lump on the lip or tongue or oral tissues. A sore which doesn't heal red spots or white patches on the tongue, cheeks, or oral tissues, persistent bleeding. If you notice any one of these symptoms, even if they are not painful, contact your family dentist or physician immediately. The earlier cancer can be detected and treated, the better the chances for a complete cure. A public service announcement of this television station and the American Dental Association."
