Bone MarrowA bone marrow biopsy involves using a large needle to extract a sample from the bone marrow to diagnose blood cancers and other conditions. Bone marrow is often extracted from the pelvic bone. Potential risks of the procedure include pain and soreness and, more rarely, bleeding and infection.
CancerCancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.
LeukemiaLeukemia is a type of cancer of the blood cells in which the growth and development of the blood cells are abnormal. Strictly speaking, leukemia should refer only to cancer of the white blood cells (the leukocytes) but in practice it can apply to malignancy of any cellular element in the blood or bone marrow, as in red cell leukemia (erythroleukemia).

Peripheral Blood Stem Cell TransplantThe peripheral blood stem cell transportation technique involves using stem cells from a patient's blood for a bone marrow transplant. Stem cells can be used to repopulate the whole bone marrow and grow new blood cells. Chemotherapy and/or radiation are used to kill diseased blood cells before a bone marrow transplant. The treatment does not involve surgery, but is nevertheless a form of transplantation.
