Pictures of mouth cancer

Pictures of changes in the mouth that could be cancerous and would need urgent referral to a specialist.

These photos give you an idea of what possible mouth cancers can look like, but remember that they might appear differently to this.

It's important to be aware of the symptoms of mouth cancer so you can contact your GP or dentist if you notice anything abnormal. There are pictures of:

  • a shallow ulcer
  • a speckled ulcer
  • tongue cancer
  • a red patch under the tongue
