Types of Leukemia – List of Common and Rare Leukemia Types

Chronic lymphocytic leukemia (CLL)

It is a slow-progressing blood cancer featuring an exaggerated replication of lymphocytes in the bone marrow. In time, excess lymphocytes spread into the blood and infiltrate organs and lymph nodes. This disease typically takes several years to develop, and patients may be asymptomatic when the disease is detected.

In a later phase of the disease, different blood cell lines in the bone marrow become affected. Thus, patients start displaying low levels of red blood cells (anemia), a reduction of blood platelets (thrombocytopenia), and reduction in functioning lymphocytes (leukopenia).
