Chronic Myeloid Leukemia
Chronic myeloid leukemia (CML) is the third-most common leukemia in children. It is much more common in adults. This slow-moving cancer occurs when excessive numbers of bone marrow stem cells develop into white blood cells and crowd out other cells that produce red blood cells and platelets in the bone marrow. Often, patients are diagnosed when they have few or no symptoms but are undergoing blood tests done for other reasons.
