A bone marrow biopsy is the removal of a sample of bone marrow for testing. The procedure is most often done on the pelvic bone. It may also be done on the sternum.

A bone marrow biopsy may be done to:
- Evaluate the counts of red and white blood cells, and platelets
- Diagnose and stage lymphoma or solid tumors
- Diagnose, monitor, and evaluate leukemias
- Evaluate iron level problems
- Evaluate for causes of unexplained spleen enlargement—splenomegaly

What to Expect
Prior to Procedure
Your doctor may do a physical exam and blood tests.
Talk to your doctor about your medications. You may be asked to stop taking some medications up to 1 week before the procedure.
Local anesthesia will be used. It will numb the area.
Description of Procedure
You may be given a light sedative. It will help you relax. The biopsy area will be cleaned and numbed.
A hollow biopsy needle will be inserted into the bone. The needle will be twisted and moved forward. This motion will allow a sample of bone marrow to enter the core of the needle. A fair amount of pressure may be used. The needle may need to be rocked. The needle will then be removed. The bone marrow sample will be inside the needle. Pressure will be applied to the puncture area. A bandage will be applied.
Immediately After Procedure
The bone marrow specimen will be examined by a pathologist. Ask your doctor when you can expect the results.
How Long Will It Take?
About 30 minutes.
Will It Hurt?
The injection of anesthesia may sting or burn. You may notice a feeling of pressure and pain when the biopsy needle is rocked. After the biopsy is done, you may feel soreness in the area for a few hours.
You should be able to resume your normal activities after your biopsy. If you have had a sedative, avoid driving or operating equipment until the effects of the medication have worn off.
