What Are MGUS and Smoldering Myeloma?

Multiple myeloma is a blood cancer that is caused by plasma cells, which are part of the immune system. When plasma cells are healthy, they produce special proteins called antibodies that fight infection in your body. When plasma cells become cancerous, they begin reproducing nonstop, and instead of producing different kinds of antibodies, the defective cells produce only one type of useless antibody.

He answers a common question: What are the chances that MGUS and smoldering multiple myeloma will turn into multiple myeloma?
