What is extramedullary plasmacytoma?

ANSWER

It's a type of cancer similar to multiple myeloma. The tumors start outside the bone marrow in the body's soft tissues. Usually, they happen in your throat, sinuses, nose, and larynx (or voice box). Up to 30% of people with extramedullary plasmacytomas will develop multiple myeloma. Treatment involves radiation therapy, surgery, or both.
