Leukemia is cancer of the white blood cells. White blood cells help your body fight infection. Your blood cells form in your bone marrow. In leukemia, however, the bone marrow produces abnormal white blood cells. These cells crowd out the healthy blood cells, making it hard for blood to do its work. In chronic lymphocytic leukemia (CLL), there are too many of a specific type of white blood cell called a lymphocyte.
CLL is the second most common form of leukemia in adults. It often occurs during or after middle age and rarely occurs in children.
