Bone Marrow Aspiration and Biopsy: What to Expect

  • Home

Introduction

Bone marrow aspiration and biopsy are important tests that help doctors understand blood and bone marrow health. These procedures can sound scary, but knowing what to expect can ease your worries. In this blog, you will learn about the bone marrow aspiration and biopsy procedure, why it is done, and how to recover safely.

What is Bone Marrow Aspiration and Biopsy?

Bone marrow is the soft tissue inside your bones. It makes blood cells that your body needs to stay healthy. A bone marrow aspiration removes a small amount of liquid bone marrow. A bone marrow biopsy takes a tiny piece of solid bone marrow tissue. Both tests are often done together. This helps doctors get a full picture of your bone marrow health.

Why It’s Done

Doctors may suggest bone marrow aspiration and biopsy for several reasons. For example, these tests help:

  • Find the cause of low or high blood cell counts
  • Diagnose blood cancers, such as leukemia or lymphoma
  • Check for infections or other bone marrow diseases
  • Monitor how well treatment is working

    • Because these tests give detailed information, they are very helpful in planning your care.

    Preparation

    Before the procedure, your doctor will explain what will happen. You may need to:

  • Tell your doctor about any medicines you take
  • Let them know if you have allergies, especially to medicines or latex
  • Arrange for someone to drive you home, if you get sedation
  • Follow any fasting instructions, if needed

    • Usually, you can eat and drink as normal unless your doctor says otherwise. However, always follow your doctor’s advice.

    The Procedure Step-by-Step

    Bone marrow aspiration and biopsy are usually done in a hospital or clinic. The whole process often takes less than an hour. Here is what you can expect:

  • Getting Ready: You will lie on your side or stomach. The doctor will clean the skin over your hip bone, which is the most common site.
  • Numbing the Area: The doctor will inject a local anesthetic to numb the skin and bone. You may feel a brief sting.
  • Bone Marrow Aspiration: A thin needle is inserted into the bone. The doctor draws out a small amount of liquid bone marrow. You might feel pressure or a quick, sharp pain.
  • Bone Marrow Biopsy: Next, a slightly larger needle takes a small piece of bone marrow tissue. You may feel more pressure, but it lasts only a few seconds.
  • Finishing Up: The doctor removes the needle and covers the spot with a bandage. You will rest for a short time before going home.

    • Most people can go home the same day. But, if you had sedation, you may need someone to help you.

    Risks and Side Effects

    Bone marrow aspiration and biopsy are safe for most people. Still, like any procedure, there are some risks. According to the CDC and other trusted sources, possible risks include:

  • Pain or soreness at the site
  • Bleeding or bruising
  • Infection at the needle site
  • Rarely, allergic reaction to anesthesia

    • Most side effects are mild and go away quickly. However, always tell your doctor if you notice anything unusual.

    Recovery and Aftercare

    After the procedure, you may feel sore for a day or two. To help with recovery, you can:

  • Keep the bandage on for at least 24 hours
  • Avoid heavy lifting or hard exercise for a day
  • Take pain medicine if needed, but only as advised by your doctor
  • Keep the area clean and dry

    • Most people return to normal activities within a day. Still, listen to your body and rest if you need to.

    When to Contact a Doctor

    Sometimes, problems can happen after the procedure. Contact your doctor right away if you notice:

  • Heavy bleeding or swelling at the site
  • Redness, warmth, or pus (signs of infection)
  • Fever or chills
  • Severe pain that does not get better

    • Early treatment can prevent more serious problems.
