This biopsy is used to evaluate organ or tumor tissue. It is also sometimes used to find out how certain treatments are working.
Complications are rare, but no procedure is completely free of risk. The potential complications will depend on the location of the biopsy. Your doctor will review a list of possible complications, which may include:
Bruise where the needle was inserted
Pain after the procedure
What to Expect
Prior to Procedure
Ask your doctor if there are any instructions you should follow before the procedure. Depending on the part of the body that the biopsy is being taken from, your doctor may ask you to:
Drink contrast material.
Have routine blood work.
Arrange for a ride home.
Talk to your doctor about your medicines. You may be asked to stop taking some medicines up to one week before the procedure, like:
You will be positioned for the easiest access to the area for biopsy. The skin will be swabbed with a cleaning solution. Anesthesia will be applied to numb the area. You will be asked to stay still. A thin, hollow needle will then be inserted through the skin to the site. The needle may need to be inserted more than once. Once the needle is in the proper position, tissue or fluid will be withdrawn. You may feel a pinch, pressure, or nothing at all. You may be monitored for bleeding or other complications. The site will be bandaged.
How Long Will It Take?
Simple biopsy (site is close to surface of skin): a few minutes (in most cases)
Deeper biopsy or one that is guided by an ultrasound or CT scan: 30-90 minutes
Will It Hurt?
The amount of discomfort you feel depends on the part of the body that is being examined. The anesthesia and sedative will prevent pain. You may feel a pinch or pressure. If you feel pain, tell the doctor right away. After the procedure, the site will be tender.
Be sure to follow your doctor’s
instructions. In general, you should check the insertion site and keep it clean.
The sample will be examined by a specialist. The results are usually ready in a few days. Your doctor will talk to you about the results.
