C92: Myeloid leukaemia

Myeloid leukaemia is a group of blood cancers that originates from the malfunctioning of bone marrow cells, which is the soft tissue found in the center of bones where blood cells are produced. This interference causes the production of an excessive amount of abnormal white blood cells known as myeloid cells. Types within this group include acute myeloid leukaemia (AML), chronic myeloid leukaemia (CML), and other variants, all differing principally by their rate of progression and maturity of the white blood cells. Common symptoms include fatigue, fever, bleeding or bruising easily, weight loss, and frequent infections due to a compromised immune system. They are generally not contagious and their precise causes are unknown, but factors such as high doses of radiation exposure, certain chemicals and genetic disorders may increase the risk. The affected systems include the circulatory (blood) and immune system.
