Delayed Diagnosis of Oral Cancer
Dentists are often the first clinicians to see the signs of oral cancer. When those signs are dismissed, the consequences can be catastrophic.

The signs
What every dentist should recognise
- An ulcer that has not healed after three weeks.
- A red or white patch on the tongue, gum or cheek lining.
- Unexplained lumps in the mouth or neck.
- Persistent hoarseness or difficulty swallowing.
The standard
Refer urgently, always
NICE guidance requires urgent (two-week) referral for any suspicious oral lesion. A dentist who watches and waits, or attributes the lesion to trauma without investigation, is departing from accepted practice.
The impact
What delay costs
Early-stage oral cancer has a five-year survival of over 80%. Delayed diagnosis often means more aggressive surgery, disfigurement, loss of speech or swallowing function — and a far worse prognosis.
