LAB TEST
Biopsy
A biopsy is the removal of a small piece of tissue for lab examination.
How the Test is Performed

How to Prepare for the Test
Before scheduling the biopsy, tell your provider about any medicines you are taking, including herbs and supplements. You may be asked to stop taking some for a while.

How the Test will Feel
With a needle biopsy, you may feel some discomfort at the site of the biopsy. Local anesthesia is injected to lessen the pain that you would feel. In an open or laparoscopic biopsy, general anesthesia is often used so that you will be pain free.
Why the Test is Performed
A biopsy is most often done to examine tissue for disease.
Normal Results
The tissue removed is normal.
What Abnormal Results Mean
An abnormal biopsy means that the tissue or cells have an unusual structure, shape, size, or condition. This may mean you have a disease, such as cancer or another condition, but it depends on your biopsy.
Risks
Risks of a biopsy include: Bleeding Infection
Considerations
There are many different types of biopsies and not all are done with a needle or surgery. Ask your provider for more information about the specific type of biopsy you are having.
