Signs & Warning Symptoms
Early oral cancer rarely hurts. That's part of why it goes unnoticed. These are the signs worth checking — especially if anything lasts longer than 2 weeks.
Red or white patches
A persistent red (erythroplakia) or white (leukoplakia) patch inside the mouth that doesn't scrape off. Red patches are especially concerning.
Sores that don't heal
A mouth or lip sore lasting longer than 2 weeks. Canker sores typically heal in 7–10 days; anything longer deserves evaluation.
Lumps or thickening
A new lump, bump, or area of thickening in the cheek, tongue, gum, or neck — especially if it's painless.
Numbness or pain
Unexplained numbness, tenderness, or pain in the mouth, face, tongue, or neck.
Difficulty swallowing or chewing
Trouble swallowing, chewing, or moving the jaw or tongue — or the feeling that something is stuck in your throat.
Ear pain with no ear problem
Ongoing ear pain without any ear infection can sometimes signal an issue at the back of the tongue or throat.
Voice changes
Persistent hoarseness or a change in your voice that lasts more than 2 weeks.
The 2-week rule
If any of the above lasts longer than 2 weeks, see a dentist or doctor. Most of the time it turns out to be nothing serious — but catching oral cancer early changes everything.
