What is a bone marrow biopsy, and how is it done?
Bone marrow is the soft tissue found in the middle of most large bones which produces white blood cells, red blood cells and platelets. A biopsy is a small sample of tissue. There are two main sorts of bone marrow biopsy – an aspiration or a trephine biopsy. If you’re having a biopsy to see if you have pernicious anaemia, you will probably have an aspiration.
