About multiple myeloma
What is multiple myeloma?
Multiple myeloma is the third most common form of blood cancer globally. It is a cancer of the plasma cells, a type of white blood cell found primarily in the bone marrow.
Healthy plasma cells are a vital part of the immune system, responsible for producing antibodies that help the body fight infections. In multiple myeloma, these plasma cells become abnormal, multiply uncontrollably and accumulate in the bone marrow.
These cancerous cells, called myeloma cells, crowd out healthy blood cells and produce abnormal proteins that damage the body. Unlike some cancers that form a single tumour, multiple myeloma often affects multiple areas of the bone marrow throughout the body.
Multiple myeloma is a complex disease that can evolve over time.
After initial treatment, the disease often changes and can come back (known as relapse) or may not respond effectively to medication (called refractory disease).
