India has among the highest rates of oral cancer in the world, driven by gutka, khaini and pan masala. It is one of the few cancers you can see developing in a mirror.
The scale of the problem
Oral cancer accounts for a very large share of male cancers in India, and the great majority of cases are attributable to smokeless tobacco — gutka, khaini, zarda, pan masala with tobacco — often combined with areca nut and alcohol.
It is also one of the few cancers preceded by clearly visible changes that appear months to years beforehand. Anyone who uses tobacco can check for them, and any dentist or doctor can identify them in a two-minute examination.
Pre-cancerous changes to look for
- Leukoplakia — a white patch that cannot be wiped away
- Erythroplakia — a red velvety patch, which carries a higher risk than white patches
- Oral submucous fibrosis — progressive stiffening of the cheeks with burning on spicy food and a gradually reducing mouth opening, strongly linked to areca nut
- A rough, thickened or leathery area at the site where tobacco is habitually held
Worth knowingDifficulty opening the mouth fully — if you cannot fit three of your own fingers vertically between your teeth — suggests oral submucous fibrosis, a recognised pre-cancerous condition.
- A mouth ulcer that has not healed in three weeks
- A lump or thickening in the cheek, tongue or floor of the mouth
- A white or red patch anywhere in the mouth
- Persistent sore throat or a feeling that something is caught
- Difficulty chewing, swallowing or moving the tongue or jaw
- Numbness of the tongue or lip
- Loosening of teeth without dental cause, or dentures that no longer fit
- Unexplained bleeding in the mouth
- A neck lump lasting more than three weeks
Examining your own mouth
Once a month, in good light before a mirror: pull the lips out and look at the inner surfaces and gums; pull each cheek outward and inspect the inner lining, including the back where tobacco is often held; stick out the tongue and look at the top, then lift it and examine the underside and the floor of the mouth; tilt your head back and look at the roof of the mouth; then feel along both sides of the neck and under the jaw for lumps.
It takes two minutes. Anything that persists beyond three weeks goes to a doctor.
Quitting
Risk begins falling from the day of quitting and continues to fall for years. Even long-term users benefit substantially. The National Tobacco Quitline (1800-11-2356) offers free counselling in regional languages, and nicotine replacement therapy is available and effective.
Practical steps that help: choose a quit date and tell your family; remove all tobacco and associated items from the house and vehicle; identify your trigger situations — after meals, with tea, with friends — and plan a specific substitute for each; and treat a lapse as a stumble rather than a failure. Most people who quit successfully have made several attempts.
Key takeaways
- Oral cancer is preceded by visible white or red patches, often for months or years.
- Any mouth ulcer lasting more than three weeks needs assessment.
- Reduced mouth opening suggests oral submucous fibrosis, a pre-cancerous condition.
- Risk begins falling from the day tobacco use stops, at any age.
