CLL and SLL are staged based on the findings from your clinical examination. Knowing the stage of your CLL or SLL helps your doctor determine the extent of your disease and monitor its progression over time.

CLL in Canada is staged using the classic or modified Rai Staging System.  SLL is staged using the Ann Arbor Staging System.  You can find out more about each system in the links below.
