Oral cancer is a heterogeneous group of cancers arising from different parts of the oral cavity, with different predisposing factors, prevalence, and treatment outcomes. It is the sixth most common cancer reported globally with an annual incidence of over 300,000 cases, of which 62% arise in developing countries.
There is a significant difference in the incidence of oral cancer in different regions of the world, with the age-adjusted rates varying from over 20 per 100,000 population in India, to 10 per 100,000 in USA, and less than 2 per 100,000 in the Middle East. ). In India, it is the most prevalent cancer in males as well as the third most common in females
Since, the oral cavity is more accessible to complete examination, it could be used in early detection of precancerous and cancerous lesions, but due to ignorance and/or inaccessibility of medical care, the disease usually gets detected in later stages.
Putting a stop to the soaring statistics of oral cancer in the region and considering the face that India ranks first in the prevalence of oral cancer has raised the need to curb the disease.
