A bone marrow biopsy is the removal of tissue inside of a bone with a hallow needle. The procedure is performed at either a doctor's office or hospital. Local anesthetic is injected into the skin before the biopsy to numb only the skin. This test is often performed when a blood test with blood cell types and numbers is abnormal.
