Myeloma (also known as multiple myeloma) is a cancer of the bone marrow. Myeloma begins in the blood’s plasma cells, a type of white blood cell that is made in the bone marrow. These plasma cells are part of the immune system. Bone marrow is the centre of blood cells production and is found in multiple areas of the body (hence the name multiple myeloma).
Normal plasma cells produce antibodies that fight infection (also called immunoglobulins). Myeloma cells are abnormal plasma cells, which only release one type of antibody known as paraprotein. These It is often through the measurement of this paraprotein that myeloma is diagnosed and monitored.
