What is Chewing Tobacco?
Chewing tobacco refers to a variety of tobacco products that are placed between the cheek and gum or teeth and slowly absorbed into the bloodstream.
Common Types of Chewing Tobacco:
- Khaini– Tobacco mixed with slaked lime
- Gutkha– A mixture of tobacco, areca nut, and flavorings
- Paan with tobacco– Betel leaf filled with areca nut, slaked lime, and tobacco
- Loose tobacco– Used directly by chewing or placing inside the mouth
These products are widely available and used by individuals across various socio-economic backgrounds.
How Does Chewing Tobacco Cause Cancer?
The risk of cancer from chewing tobacco comes from harmful chemicals that are absorbed directly into the tissues of the mouth and throat.
Key Carcinogens in Chewing Tobacco:
- Tobacco-specific nitrosamines (TSNAs)– One of the most potent cancer-causing agents in tobacco
- Heavy metals– Such as arsenic and lead that damage cells
- Formaldehyde– A chemical that disrupts cell health
- Polycyclic aromatic hydrocarbons– Found in processed tobacco, causing DNA mutations
The Process:
- These chemicals damage the cells lining the mouth and throat
- DNA damage leads to uncontrolled cell growth
- Tumors develop over time, leading to cancer
