Oropharynx lesion biopsy

How the Test is Performed:
A topical anesthetic is usually used (for large lesions or lesions of the throat, a general anesthetic may be needed). The entire lesion, or a small portion of larger lesions, is removed and sent to the laboratory for analysis. If a growth is present in the mouth or throat, this test may be part of tumor removal/resection.

How to Prepare:
If a local or topical anesthetic is to be used, there is no special preparation. If the test is to be part of a tumor removal or if general anesthetic is to be used, fasting for 6 to 8 hours may be necessary.

Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust.
