Tamil Nadu has reported around 8,000 new oral cancer cases in 2025, raising concerns over late detection and increasing smokeless tobacco use.
As per the Tamil Nadu Cancer Registry Programme, incidence is higher in men (11.6 per 1,00,000) than in women (5.4 per 1,00,000).
India accounts for nearly one-third of global oral cavity cancer cases, with tobacco chewing, gutka, khaini, zarda, areca nut, and beedi smoking as major causes.
Nearly 70–80% of cases in India are diagnosed at advanced stages, leading to a five-year survival rate of around 50%.
