Can you tell me what chronic lymphocytic leukemia (cll) is?

CLL: Cll is an indolent (slow-growing) cancer in which too many immature lymphocytes (white blood cells) are found mostly in the blood and bone marrow and lymph glands . Watchful waiting is majority done until any indication present to start treatment. However, there is subtype of cll which behaves more agressively and requires treatment to be started earlier. See more at : www.Lls.Org, www.Cancer.Gov.

See below...: Cll stands for chronic lymphocytic leukemia, a form of blood cancer. Cll is usually not an aggressive form of leukemia and has a relatively good prognosis overall. Many patients are asymptomatic for a long period of time (years) and do not need any form of therapy unless there are symptoms or adverse prognostic factors.
