Chronic Lymphocytic Leukemia

Chronic Lymphocytic Leukemia (CLL) is a slow-growing cancer in which too many immature white blood cells are found mostly in the blood and bone marrow. In later stages, these immature white blood cells can be found in the lymph nodes. When this occurs, it is also commonly called Small Lymphocytic Lymphoma (SLL).
