In a bone marrow aspiration, a healthcare professional uses a thin needle to remove a small amount of liquid bone marrow. It is usually taken from a spot in the back of the hipbone, also called the pelvis. A bone marrow biopsy is often done at the same time. This second procedure removes a small piece of bone tissue and the enclosed marrow.
