Background information on CML

CML is a rare cancer of the bone marrow and white blood cells. It is one of four main types of leukemia, also called chronic myeloid leukemia or chronic myelogenous leukemia. This form of leukemia is characterized by the increased and unregulated growth of myeloid cells in the bone marrow and the accumulation of these cells in the blood. CML has three phases and it's usually diagnosed in its chronic phase when treatment is very effective for most patients. Hematologists and oncologists are specialists who treat people who have CML or other types of blood cancer. If you or a family member has been diagnosed with CML we encourage you to consult your doctor for your diagnostic test, what the results mean and for any treatment advice. 

If you want to learn more about chronic myeloid leukemia, how CML is developed and how the disease is diagnosed and treated we have compiled a couple of reliable resources for you that all provide patient-friendly information on CML.
