Chronic Lymphocytic Leukemia

Chronic lymphocytic leukemia or CLL causes a slow increase in the number of white blood cells in the bone marrow. The cancerous cells spread from the bone marrow to the blood, and can also affect the lymph nodes and other organs. CLL eventually causes the bone marrow to fail and weakens the immune system.
