Chronic myelomonocytic leukaemia (CMML) is a type of leukaemia which are cancers of the blood-forming cells of the bone marrow. In adults blood cells are formed in the bone marrow by a process that is known as haematopoiesis. In CMML there are increased numbers of monocytes and immature blood cells (blasts) in the peripheral blood and bone marrow as well as abnormal looking cells (dysplasia) in at least one type of blood cell.
