An estimated 120,200 cases of oral cancer diagnosed in 2022 globally have been linked to smokeless tobacco or areca nut consumption. According to the study, this accounts for over 30 per cent of all oral cancer cases.
The study used the rates of current use of smokeless tobacco or areca nut products from national surveys with the risks of oral cancer to estimate the number of oral cancer cases likely due to smokeless tobacco or areca nut.
The results
The study found that an estimated 77 per cent of all oral cancer cases were among male patients and 23 per cent among female patients. Also, over 95 per cent of oral cancer cases attributable to smokeless tobacco or areca nut were in low-income and lower-middle-income countries.
