Nearly 267 million adults (15 years and above) in India (29% of all adults) are users of tobacco, according to the Global Adult Tobacco Survey India, 2016-17. Two in every five females. Nearly half of all male population and two in every five females in the WHO South-East Asia Region (SEAR) consume some form of tobacco. Tobacco is one of the most important risk factors for premature death globally. More than 60 toxic chemicals in tobacco can invade the body’s various systems. Human papillomavirus (HPV) is known to be associated with several types of human cancer, including cervical, vulvar, vaginal, penile, anal, and head-and-neck cancers. Among these cancers, HPV-associated head-and-neck cancers, inclusive of oropharyngeal squamous cell carcinoma (OSCC) and oral cavity squamous cell carcinomas (OCSCC). The high-risk type 16 constitutes the most prevalent HPV type globally, being detected in almost 60% to 80% of head-and-neck cancers. Therefore there is a need for appropriate and timely detection of OSCC and its premalignant counterparts with the right usage of proper biopsy techniques for a better prognosis.
