Busulfan is used to treat chronic myeloid leukaemia (CML). This is a cancer of blood-forming cells in the bone marrow. Abnormal cells gradually fill the bone marrow and spill into the bloodstream, which increases the number of white cells in your blood. The disease typically develops very slowly and symptoms such as anaemia, bleeding problems or infections may not occur for many years after the start of the condition.
