A global study has revealed that one-third of oral cancer cases are linked to the use of smokeless tobacco and areca nut. In 2022 alone, over 120,000 cases were attributed to these substances, highlighting the significant health risk they pose.

The highest prevalence of oral cancer cases caused by smokeless tobacco and areca nut was observed in South-Central Asia, where nearly 90% of such cases occurred. Additionally, over 95% of these cases were found in low- and middle-income countries, reflecting the global inequality in health burdens.

Interestingly, the study found no significant link between oral cancer and the use of Swedish snus, a form of smokeless tobacco used in Northern Europe. This discovery underscores the need for region-specific health policies and preventive measures.

Smokeless tobacco is consumed in various forms, such as chewing, sucking, or inhaling, while areca nut can be used alone or in betel quid. Both substances pose severe risks to oral health without the need for burning, unlike smoking.

With millions of people using these harmful products worldwide, public awareness and prevention campaigns are critical. This study emphasizes the need for global efforts to reduce the consumption of smokeless tobacco and areca nut to prevent further increases in oral cancer cases.
