Multiple myeloma (also known as myeloma or plasma cell myeloma) is a hematologic cancer, meaning it develops in the blood. It is a cancer of the plasma cell, an important part of the immune system that produces immunoglobulins (antibodies) to help fight infection and disease. Myeloma is called "multiple myeloma" because multiple patches or areas of bone marrow are typically affected.
