What is a "bone marrow biopsy"?

There are quite a few reasons to do bone marrow biopsy from a cancer perspective, and specifically relating to diagnosis of lymphoma or cancer. We do bone marrow biopsy to evaluate if there is presence of cancer inside the bone marrow. Presence of cancer inside the bone marrow increases the stage of your illness, especially lymphoma. Lymphoma diagnosis with bone marrow involvement is a much more aggressive and much more advance presentation than a lymphoma that happens to not be in the bone marrow. It enables us to determine the stage of cancer, prognosis of a particular cancer, and determine what we need to do in terms of treatment.
