What is Chronic Myeloid Leukemia?

Chronic myeloid leukemia (CML), also called chronic myelogenous leukemia, is a type of cancer affecting the blood and bone marrow. Bone marrow is the soft, spongy center of the bone where blood cells form. In CML, the bone marrow produces too many white blood cells. White blood cells normally help fight infection and disease. But in CML, the white blood cells become abnormal. They begin to grow too fast and crowd out normal healthy cells.
