Mouth Biopsy Information 

This information has been designed to improve your understanding of any forthcoming treatment and contains answers to many of the commonly asked questions. If you have any other questions that the leaflet does not answer or would like further explanation please ask.

What is a biopsy?

A biopsy is a procedure where a small piece of tissue is removed from an area so that it can be looked at closely under a microscope. The biopsy may aim to remove an area completely (an excisional biopsy).  This is usually only appropriate for small lumps or swelling.  Occasionally only a small piece of an abnormal area is removed to confirm a diagnosis (an incisional biopsy).

How is it done?

In most cases biopsies are carried out under local anaesthesia (a numbing injection) and it takes a couple of minutes to work and the biopsy will be painless. This often leaves a small wound that may require stiches.  These are usually dissolvable that may take up to four to six weeks to dissolve..

Is there much soreness or swelling afterwards?

When the anaesthetic wears off, it may be necessary to take pain killers for a few days.  Also, the area may swell slightly.

Will there be much bleeding?

The biopsy site may bleed a little, but we will make sure it has stopped before you leave along with full after care instructions.

When can I return to work?

This largely depends on your job and how you feel after the procedure. Most people are able to return to work later the same day.
