    Reasons for Procedure

    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
    • Evaluate other blood disorders or diseases that may affect the bone marrow

    Possible Complications

    Complications are rare, but no procedure is completely free of risk. If you are planning to have this procedure, your doctor will review a list of possible complications which may include:
    • Infection
    • Bleeding
    Some risk factors for complications during this procedure include:
    • Bleeding disorders
    • Infection of the skin at the biopsy site
    • Infection in the bloodstream
    • Prior radiation treatment to the biopsy site

    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.

    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 medication have worn off.

    Call Your Doctor

    Contact your doctor if your recovery is not progressing as expected or you develop complications, such as:
    • Signs of infection, including fever and chills
    • Redness, swelling, increasing pain, excessive bleeding, or any discharge from the biopsy site
    • Nausea and/or vomiting
    • Cough, shortness of breath, or chest pain
    • Joint pain, fatigue, stiffness, rash, or other new symptoms
    If you think you have an emergency, call for emergency medical services right away.
