Chronic lymphocytic leukemia
lymphoblastic leukemia characterized by over production of B-cells and their accumulation in bone marrow and blood
Chronic lymphocytic leukemia (CLL) is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell).
Early on there are typically no symptoms. Later non-painful lymph node swelling, feeling tired, fever, night sweats, or weight loss for no clear reason may occur.
Risk factors include having a family history of the disease.
