Chronic Phase CML

If you're like 9 out of 10 people with chronic myeloid leukemia (CML), you're in the chronic phase when you're diagnosed.

The chronic phase is 1 of 3 generally accepted phases or stages of CML. What sets them apart is the number of blast cells found in the blood and bone marrow. If your CML is identified while you're still in the chronic phase, you have a relatively low percentage of blast cells. Your normal white blood cells are still able to fight infection. The general goal is to keep it that way—keeping you free of symptoms.

Chronic Phase

About 90% of the people with chronic myeloid leukemia (CML) are in the chronic phase when they are diagnosed.
