Chronic lymphocytic leukemia
Chronic lymphocytic leukemia (CLL) is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell).[1][2]
Early on there are typically no symptoms.[1] Later non-painful lymph node swelling, feeling tired, fever, night sweats, or weight loss for no clear reason may occur.[1]
Risk factors include having a family history of the disease.
