The two-week rule: when a mouth ulcer needs more than ointment

India carries one of the world’s highest burdens of oral cancer, and the tragedy is that the mouth is one of the easiest places to detect cancer early. The single most useful rule for anyone is this:

Any ulcer, patch, or growth in the mouth that hasn’t healed in two weeks should be examined by a specialist.

Why two weeks?

Ordinary ulcers — from biting, sharp food, a denture edge, or stress (apthous ulcers) — heal within 7 to 14 days. An ulcer that persists past that window is no longer “ordinary” and needs a diagnosis, even if it doesn’t hurt. Early oral cancer is usually painless. Waiting for pain is waiting too long.

What we look for

• Non-healing ulcers, especially on the side of the tongue or floor of the mouth
• White patches (leukoplakia) or red patches (erythroplakia) — red carries a higher risk
• A lump or thickening you can feel with your tongue
• Loose teeth without gum disease, or numbness in the lip or chin
• Reduced mouth opening and a burning feeling with spicy food — typical of submucous fibrosis in gutka/areca users

What happens at an examination

A specialist examination takes about fifteen minutes. If a lesion looks suspicious, a small biopsy under local anaesthesia gives a definitive answer in a few days. Most biopsies come back benign — and that reassurance alone is worth the visit.

If you use tobacco, areca nut, or gutka

You are the highest-priority group for screening. Stopping the habit halts or even reverses many pre-cancerous changes; combined with annual screening, it’s the most effective insurance you can buy at any price.

Found something in your mouth that’s been there more than two weeks? Don’t watch it for another month. Get it looked at — it’s quick, and it could save your life.
