Multiple myeloma is a cancer of certain cells of the bone marrow called plasma cells. Multiple myeloma is a form of bone marrow cancer. Plasma cells normally produce our antibodies.

Causes of multiple myeloma

The cause of multiple myeloma is not known. For many, there is thought to be a premalignant stage whereby plasma cells in the bone marrow produce a seemingly benign, single type of antibody for years. This is called monoclonal gammopathy of undetermined significance, or MGUS. After 50 years of age, MGUS is present in over 3% of the population. In those with MGUS, myeloma or another cancer develops at a rate of 1% per year.
