Overview
A biopsy removes a small sample (or sometimes all) of an unusual area in the mouth so it can be examined by a pathologist. It's the most reliable way to find out exactly what a lump, ulcer or patch is. Most turn out to be harmless — a biopsy simply gives a definite answer and peace of mind.
Common questions
Does a biopsy mean something is wrong?
Not necessarily. We biopsy anything unusual or slow to heal — usually for reassurance and a clear diagnosis, not because cancer is suspected.
Is it uncomfortable?
The area is numbed first, so it's well tolerated. Any soreness afterwards is usually minor.
When do I get results?
The sample goes to a laboratory and results typically take one to two weeks. We'll discuss them and any next steps with you.
