Leukaemia is cancer (a disease caused by an uncontrolled division of abnormal cells in a part of the body) of the white blood cells. Primitive white blood cells are formed in the bone marrow then gradually change into many specialised different types of cell, and patients can get one of many types of leukaemia. White blood cells “leucocytes” are divided into two main groups, cells to do with the lymphatic systemlymphocyte” and cells to do with the bone marrow “myelocytes”. Cancer in these can cause lymphocytic (or lymphatic) leukaemia and myeloid leukaemia. In either case the onset can be sudden “acute” or gradual “chronic”. These are the main 4 types of leukemia, and of course there are few other types.

Under the microscope leukaemia white blood cells look different to the normal white cells.
