Bone marrow aspiration is a procedure that involves taking a sample from the soft tissue inside your bones. Bone marrow is the spongy tissue found inside bones. It contains cells that produce white blood cells, red blood cells, and platelets inside larger bones such as the spine. The doctor makes a small incision, then inserts a hollow needle through the bone and into the bone marrow. Using a syringe attached to the needle, the doctor withdraws a sample of the liquid portion of the bone marrow. You may feel a brief sharp pain or stinging. The aspiration takes only a few minutes.
