Chronic Lymphocytic Leukemia (CLL)

What Is CLL?

Chronic Lymphocytic Leukemia (CLL) is a slow-growing cancer of the lymphocyte, which normally resides in the blood, bone marrow, lymph glands and spleen.

CLL may be characterised by an isolated elevation in the blood lymphocyte count only, or it may be associated with enlarged lymph glands, liver and/or spleen. Its natural history resembles that of a low-grade non-Hodgkin's lymphoma with average survival exceeding 5 years.
