A tongue biopsy is a minor surgery that is done to remove a small piece of the tongue. The tissue is then examined under a microscope.
A tongue biopsy can be done using a needle.
Some types of tongue biopsies remove a thin slice of tissue. Medicine to numb the area (local anesthetic) will be used. Others are done under general anesthesia, (allowing you to be asleep and pain-free) so that a larger area may be removed and examined.
You may be told not to eat or drink anything for several hours before the test.
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 have stitches or an open sore where the biopsy was done.
