Abstract
Oral cancer is depicted by diverse geographic disparity in its incidence and prevalence, with a wide range of variation in its distribution across various parts of the world. The present review aims at focusing on the global epidemiological data of oral cancer and catalogues the available data from the past to till date on burden of oral cancer across different continents in the world. The review also suggests a few ideas on modifying the recording of the epidemiological data of the disease.
