Leukemia – Chronic Lymphocytic – CLL


Chronic lymphocytic leukemia is a type of blood cancer that weakens the immune system by affecting the type of white blood cells known as lymphocytes. Due to overcrowding in the bone marrow from the buildup of abnormal cells, other cell types may be interfered with, causing additional problems. A type of lymphocyte called B-cells are affected in 95% of CLL cases, where T-cells (another kind of lymphocyte) are involved in the second most common CLL type, T-cell prolymphocytic leukemia.
