Find out about the possible symptoms of chronic myeloid leukaemia (CML).

Getting diagnosed

Your GP will ask you about your symptoms and might arrange an urgent blood test or refer you to a specialist.


There are 2 main groups of leukaemia - acute and chronic leukaemia. They are then grouped by the type of white blood cell that is affected.


CML is divided into 3 phases: chronic, accelerated and blast. Knowing the phase helps your doctor decide which treatment you need.


Your treatment depends on the phase of your leukaemia, your general health, your age and level of fitness.
