What Is Multiple Myeloma?
Myeloma is a cancer of the plasma cells in the bone marrow. The malignant plasma cells, or myeloma cells, accumulate in the bone marrow. These myeloma cells are abnormal plasma cells that divide uncontrollably, leading to the overproduction of dysfunctional antibodies and crowding out healthy blood cells.
Anyone can get cancer of the plasma cells. However, studies show that multiple myeloma can be more prevalent in persons of African descent. Age can also be a factor — 65-74 is the average age range for diagnosis, though persons of African American and Hispanic descent are usually diagnosed at an earlier age. Multiple myeloma is also more prevalent in men than in women.

A solitary plasmacytoma is a localized tumor composed of plasma cells. It can grow inside bone, or intramedullary. It can also grow outside bone, or extramedullary or in the soft-tissue. Multiple myeloma occurs when there are multiple plasmacytomas inside or outside bone. When patients with myeloma have disease outside the bone marrow, this is called “extramedullary disease” (EMD).
