General Discussion

Multiple myeloma is a rare form of cancer characterized by excessive production (proliferation) and improper function of certain cells (plasma cells) found in the bone marrow. Plasma cells, which are a type of white blood cell, are produced in the bone marrow and eventually enter the bloodstream. Excessive plasma cells may eventually mass together to form a tumor or tumors in various sites of the body, especially the bone marrow. If only a single tumor is present, the term solitary plasmocytoma is used. When multiple tumors are present, the term multiple myeloma is used. Plasma cells are a key component of the immune system and secrete a substance known as myeloma proteins (M-proteins), a type of antibody. Antibodies are special proteins that the body produces to combat invading microorganisms, toxins, or other foreign substances. Overproduction of plasma cells in affected individuals results in abnormally high levels of these proteins within the body.

Major symptoms of multiple myeloma may include bone pain, especially in the back and the ribs; low levels of circulating red blood cells (anemia) resulting in weakness, fatigue, and lack of color (pallor); and kidney (renal) abnormalities. In most cases, affected individuals are more susceptible to bacterial infections such as pneumonia. The exact cause of multiple myeloma is unknown.
