Chronic myeloid leukaemia. Digitised coloured light micrograph of cancerous blood cells in chronic myeloid leukaemia (CML). The large blue cells are abnormal white blood cells. The small pink cells are normal red blood cells. Chronic my- eloid leukaemia causes uncontrolled proliferation of certain types of white blood cells in bone mar- row (granulocytes, neutrophils & polymorphonuclear leukocytes). Normal blood cell production in the marrow is impaired, leading to symptoms such as fever, tiredness and weight loss. CML eventually develops into acute leukaemia, which is usually fatal. Treatment includes anti-cancer drugs and bone marrow transplants. Magnification unknown.
