Multiple myeloma is a cancer formed by malignant plasma cells. Normal plasma cells are found in the bone marrow and are an important part of the immune system. The immune system is made up of several types of cells that work together to fight infections and other diseases. Plasma cells are mainly found in the bone marrow. They mature from a type of cells of the immune system (the B-cells) and make the antibodies that help the body attack and kill germs. When plasma cells become cancerous and grow out of control, they can produce a tumour called a plasmacytoma.
These tumours generally develop in a bone, but they are also rarely found in other tissues. One single cancerous plasma cell is called an isolated (or solitary) plasmacytoma. More plasmacytomas constitute a multiple myeloma 
Multiple myeloma is the 23rd most common type of cancer in the world. In 2012 114,000 new cases of multiple myeloma were diagnosed 
. Multiple myeloma is considered to be incurable but treatable. Remissions may be induced with steroids, chemotherapy, proteasome inhibitors, immunomodulatory drugs such as thalidomide or lenalidomide, and stem cell transplants. Radiation therapy is sometimes used to reduce pain from bone lesions 
. New immunotherapies are offering new hope to multiple myeloma clinicians and patients
