Myeloma is a cancer of plasma cells (mature B-lymphocytes), which are a type of white blood cell that form part of the immune system. Myeloma may also be called multiple myeloma or plasma cell myeloma. 

Leukaemia is the name given to a group of cancers that develop in the bone marrow. Under normal conditions, the bone marrow contains a small number of healthy immature blood cells (blast cells) which mature and develop into red blood cells, white blood cells and platelets, which are eventually released into the bloodstream.
