Chronic lymphocytic leukemia (CLL) is a type of cancer that starts from cells that become certain white blood cells(called lymphocytes) in the bone marrow. The cancer (leukemia) cells start in the bone marrow but then go into the blood.In CLL, the leukemia cells often build up slowly over time, and many people don't have any symptoms for at least a few years. In time, the cells can spread to other parts of the body, including the lymph nodes, liver, and spleen.
Chronic Lymphocytic Leukemia (CLL) is a slow-growing cancer of lymphoid cells that usually affects people over 55 years of age. It is estimated to affect about 16,000 people in the U.S. every year. It almost never occurs in children or adolescents.
