Myeloma
Myeloma, also known as multiple myeloma, is a type of blood cancer that originates in the plasma cells of the bone marrow. Plasma cells are a type of white blood cell responsible for producing antibodies that help fight infection. In multiple myeloma, abnormal plasma cells (myeloma cells) multiply uncontrollably, crowding out healthy blood cells and producing abnormal proteins that can cause damage to various parts of the body, including bones, kidneys, and the immune system.
