Oral cancer screening saves lives

Oral cancer is the 8th most common cancer in men and ranks 14th among women worldwide. There were 274,300 new cases and 145,500 deaths worldwide in 2002. Two-thirds of this burden are borne by developing countries, and over 30% by India alone. A high rate of oral cancer has been recorded in the Indian subcontinent, central and eastern Europe, parts of France, southern Europe, South America, and Oceania.
