Chronic Myeloid Leukemia (CML) is a rare cancer of the blood and bone marrow. It results in an excessive production of white blood cells by the bone marrow. CML is caused by a genetic defect on chromosome 22 that results from an exchange of genetic material between chromosomes 9 and 22. This abnormal form of chromosome 22 is called the Philadelphia chromosome. The disease is often found accidentally during a routine blood test. CML mainly affects adults. It is more common in people between the ages of 50 and 60.
