Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma
Chronic lymphocytic Disease generally characterized by the overproduction of abnormal or immature white blood cells that circulate or are present in the blood. (CLL) and small lymphocytic lymphoma (SLL) are cancers that affect A type of white blood cell. Lymphocytes, carries along by the lymph fluid, are part of the immune system and fight infection.. CLL and SLL are essentially the same disease, with the only difference being the location where the Abnormal cell growth that cannot be controlled by the body's natural defenses.
