The short explanation
A red or white patch inside the mouth in someone who has used tobacco for years should be checked by a dentist or doctor soon, even if it does not hurt. Red patches, called erythroplakia, and white patches, called leukoplakia, can be harmless, but some can be early changes that may lead to mouth cancer. Red patches in particular are more likely to show these changes. Mouth cancer is common in India, especially among people who chew tobacco, paan or gutka. Finding changes early makes treatment simpler and more effective. A doctor may suggest a small biopsy to check the cells.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Stopping tobacco reduces the risk of further changes. Support to quit is available through doctors and quitlines.
- Other warning signs include a lump, an ulcer that does not heal, difficulty opening the mouth, or difficulty swallowing.
- Government hospitals and cancer centres offer oral screening.
- Painless patches are often ignored, so it is good that you are paying attention.
