Myeloma (also called multiple myeloma) is a cancer of plasma cells in your bone marrow.
Plasma cells are a type of white blood cell made in your bone marrow, which is found in the centre of large bones. In myeloma, abnormal plasma cells build up in your bone marrow and release large amounts of a single antibody called a paraprotein.
