According to wikipedia, multiple myeloma (also known as MM, myeloma, plasma cell myeloma, or as Kahler's disease) is a type of cancer of plasma cells which are immune system cells in bone marrow that produce antibodies. Its prognosis, despite therapy, is generally poor, and treatment may involve chemotherapy and stem cell transplant. It is part of the broad group of diseases called hematological malignancies.
Rest in peace, Vern
