Causes of mouth cancer

We do not know the exact cause of mouth cancer, but some things increase your risk:

Diagnosing mouth cancer

Your doctor or dentist will listen to your symptoms and examine your mouth.

If there is a possible cancer growth, they will take a sample (biopsy) to be looked at in a laboratory.

If cancer is found, you may have tests to see how far it has spread such as an X-ray, CT or MRI scan.

Treating mouth cancer

Preventing mouth cancer
