A tongue biopsy is surgery to remove a piece of the tongue to look at under a microscope.
How is the Test Performed?
A tongue biopsy can be done using a needle.
- You will get numbing medicine at the place where the biopsy is to be done.
- The health care provider will gently stick 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. You will be asleep and pain-free so that a larger area may be removed and examined.
Preparation for the Test
You may be told not to eat or drink anything for several hours before the test.
How will the Test Feel?
Your tongue is very sensitive so a needle biopsy may be uncomfortable even when numbing medicine is used.
Your tongue can be tender or sore, and it may feel slightly swollen after the biopsy. You may be stitches or an open sore where the biopsy was done.
Why is the Test Performed?
The test is done to find the cause of abnormal growths or suspicious-looking areas of the tongue.
