Definition Return to top
An oropharynx lesion biopsy is surgery in which tissue from an abnormal growth or mouth sore is removed and checked for problems.
How the Test is Performed Return to top
A painkiller or numbing medicine is first applied to the area. For large sores or sores of the throat, general anesthesia may be needed. All or part of the lesion is removed and sent to the laboratory to check for problems. If there is a growth in the mouth or throat, the biopsy may be the first part of tumor removal.
How to Prepare for the Test Return to top
If a simple painkiller or local numbing medicine is to be used, there is no special preparation. If the test is part of a tumor removal or if general anesthesia is to be used, you may be told not to eat for 6 - 8 hours before the test.
