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 one week before the procedure, like:

  • Anti-inflammatory drugs
  • Blood thinners
  • Anti-platelet medications

Anesthesia  

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 or 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.

Post-procedure Care  

At Home  

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 medicine have worn off.

Follow all of your doctor's instructions .
