What is MM

Multiple myeloma (MM) is a type of bone marrow cancer of the white blood cell — more specifically, of the plasma cell. Normal plasma cells help fight infections by making antibodies that recognise and attack germs, but MM causes cancer cells to accumulate in the bone marrow where they crowd out healthy blood cells, impairing their ability to fight infections. Rather than producing helpful antibodies, the cancer cells produce abnormal proteins called monoclonal (M) proteins, which can impair kidney functions. MM affects several other areas of the body such as the spine, skull, pelvis, and ribs. The signs and symptoms can vary between people, and there may be no signs or symptoms present in early disease (Mayo Clinic, 2015).

The incidence of MM varies across the eight major markets (8MM: the US, France, Germany, Italy, Spain, the UK, Japan and urban China) and a higher proportion of diagnosed incident cases in all markets except urban China were diagnosed at stage II, according to the revised-international staging system (R-ISS).
