Chewing Doma (Fermented Betel Nut): Culture versus Cancer?

Area of Science:

• Oncology
• Public Health
• Cultural Anthropology

Background:

• Areca nut (betel quid) consumption is a widespread cultural practice in South Eastern countries.
• Traditional fermentation of areca nut into 'doma' in Bhutan enhances its carcinogenic properties.
• Doma chewing is prevalent, with 45% of the Bhutanese population consuming it.

Purpose of the Study:

• To highlight the strong association between doma consumption and oral and upper gastrointestinal cancers in Bhutan.
• To propose a public health intervention to curb the incidence of these cancers.

Main Methods:

• Observational analysis of areca nut consumption patterns in Bhutan.
• Epidemiological correlation between doma chewing and cancer prevalence.
• Development of a targeted public health slogan for intervention.

Main Results:

• Doma consumption is identified as the primary cause of oral cavity, oropharynx, hypopharynx, and larynx cancers in Bhutan.
• A significant public health challenge exists due to the high prevalence of doma chewing.

Conclusions:

• Fermented areca nut (doma) poses a severe cancer risk in Bhutan.
• A public health campaign with the slogan "Don't chew your way to cancer, say no to doma" is proposed.
• This intervention aims to reduce the burden of oral and esophageal cancers in Bhutan.
