Description
U. Venkatesh and a large multicentre team assess bidi smoking and cancer risk across India in a 2026 case-control study. Bidis, small hand-rolled cigarettes, are widely smoked, yet product-specific cancer evidence from many centers was scarce. Eight hospitals in seven states enrolled about two thousand patients with confirmed cancer during 2024 and 2025. A similar number of controls without cancer history joined. Detailed tobacco habits were recorded for each person.
Tobacco use was more common among cases than controls. Exclusive bidi smokers showed roughly triple the adjusted odds of cancer compared with non-users, and smokeless tobacco also raised odds. Mixed and multiple product patterns were examined for risk, spread at diagnosis and treatment choices. Product-specific counseling gains stronger local evidence from these results.
