Multiple Myeloma

Multiple myeloma, also referred to as myeloma, is a cancer of bone marrow plasma cells.

In myeloma, abnormal plasma cells ("myeloma cells") grow uncontrollably and produce excess amounts of proteins ("M-proteins").

The uncontrolled growth of myeloma cells leads to less room for healthy blood cells as the myeloma overtakes the bone marrow space. The myeloma cells can also cause tumors in the bone marrow that destroy bone leading to fractures and high levels of calcium in the blood.

The M-proteins made by the myeloma cells can cause kidney damage.
