Chronic Myeloid Leukemia (CML)
CML is a chronic or slow-growing leukemia, at least at first. It begins in the bone marrow with abnormalities of blood-forming cells, and over time, these cancerous cells make their way into the bloodstream and around the body. But while CML might start slowly, it can shift into an acute form that may affect any organ.
CML is also different in that it has a known association with an abnormal chromosome called the Philadelphia chromosome. CML diagnoses account for 10-15% of all types of leukemia and tends to strike older people. The average age for a first diagnosis is 67 years old.
