Bone marrow aspiration is a procedure that takes out a small amount of bone marrow fluid through a needle. Bone marrow biopsy uses a needle to take out a small amount of bone with the marrow inside it. These samples are then checked under a microscope. The hip bone is the most commonly used area for these procedures.
Aspiration and biopsy are often done to find a blood problem or an infection. They also may be used to find out if a cancer has spread to the bone marrow.
You may get medicine to help you relax before the procedure. The doctor will inject numbing medicine in the skin over your bone. He or she will put a needle through your skin and into your bone to reach the bone marrow. You may feel pressure or some dull pain during the procedure. After the doctor takes the sample, he or she will remove the needle. The doctor may need to take more than one sample. This can come from the same spot or from a different area on your body. When the procedure is done, the doctor or a nurse will put pressure on the area to stop any bleeding.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
