Quick Answer

Oral cancer screening takes a few minutes. A doctor or dentist checks for white or red patches, ulcers, lumps and areas of thickening, and feels the neck for enlarged lymph nodes. People who use tobacco, gutka, areca nut or alcohol should be screened regularly. Any suspicious area may need a biopsy.

Oral cancer screening is a simple visual and physical examination of the mouth, lips, tongue, gums and throat to look for signs of cancer or pre-cancerous changes. In India, where mouth cancer is common due to tobacco and areca nut use, regular screening can help find problems early, when treatment is most successful.

Who Should Be Screened?

  • Tobacco smokers or chewers
  • Users of gutka, paan, khaini or areca nut
  • Regular alcohol users
  • People over 30 with risk habits
  • Those with a history of pre-cancerous lesions
  • People with reduced mouth opening
  • Anyone with a non-healing mouth sore

India's national programmes recommend oral screening for adults, especially those with risk factors.

What Happens During Screening?

  1. The doctor looks inside your mouth with a light
  2. Checks the lips, gums, cheeks, tongue, floor of mouth and palate
  3. Feels for lumps in the mouth and neck
  4. Asks about habits and symptoms

It is painless and quick.

What Are Doctors Looking For?

  • White patches (leukoplakia)
  • Red patches (erythroplakia)
  • Non-healing ulcers
  • Lumps or thickened areas
  • Reduced mouth opening (oral submucous fibrosis)
  • Enlarged neck lymph nodes

What If Something Is Found?

  • A biopsy may be taken
  • Some pre-cancerous lesions are monitored closely
  • Others may be removed
  • If cancer is diagnosed, staging tests and treatment planning follow

How to Self-Check at Home

  • Use a mirror and good light
  • Check lips, gums, cheeks and tongue, including underneath
  • Look at the roof and floor of your mouth
  • Feel for lumps in the mouth and neck
  • Do this once a month

Report any change lasting more than two weeks.

How Can You Lower Your Risk?

  • Quit tobacco and areca nut in all forms
  • Limit alcohol
  • Maintain oral hygiene
  • Visit a dentist regularly
  • Eat fruits and vegetables

Key Takeaways

  • Oral cancer screening is quick and painless.
  • Tobacco and areca nut users need regular checks.
  • White and red patches can be pre-cancerous.
  • Biopsy confirms suspicious findings.
  • Monthly self-checks help early detection.
