Biopsy - tongue

Definition    Return to top

A tongue biopsy is surgery to remove a piece of the tongue for examination under a microscope.

How the Test is Performed    Return to top

A tongue biopsy can be done using a needle. After numbing the area, the health care provider gently sticks the needle into the tongue and removes a tiny piece of tissue.

Some types of tongue biopsies remove a thin slice of tissue. Others are done under general anesthesia (asleep and no pain) so that larger areas, such as lesion, growth, or other abnormal area of the tongue, may be removed and examined. See also: Surgical excision

How to Prepare for the Test    Return to top

You may be told not to eat or drink anything for several hours before the test.

How the Test Will Feel    Return to top

A needle biopsy is often somewhat uncomfortable even with use of an anesthetic, because the tongue is quite sensitive. After the biopsy, the tongue can be tender or sore, and it may feel slightly swollen.

Why the Test is Performed    Return to top

The test is done to determine the cause of abnormal growths, lesions, or suspicious-appearing areas of the tongue.

Normal Results    Return to top

There is normal tongue tissue, with no abnormal inclusions or cellular changes.
