What do I need to know about an oral lesion excision?

An oral lesion excision is surgery to remove a sore, ulcer, or patch (lesion) from inside your mouth. This includes the inner lip or cheek lining, gums, tongue, and floor and roof of the mouth. Removal may be the only treatment needed for the lesion, or may be part of your treatment plan.

What are the risks of an oral lesion excision?

You may bleed more than expected or develop an infection. Depending on where the lesion is, removal may cause nerve damage. Your surgeon may not be able to remove all of the unhealthy tissue. Even with surgery, you may develop another oral lesion. Cancer cells may still spread or come back. You may have scarring from where the skin tissue was removed.
