For certain cancers, the American Cancer Society recommends screening tests in people without any symptoms, because they are easier to treat if found early. But for chronic lymphocytic leukemia (CLL), no screening tests are routinely recommended at this time .
Sometimes, CLL is found when routine blood tests are done for other reasons. For instance, a person's white blood cell count may be very high, even though he or she doesn't have any symptoms.
If you notice any symptoms that could be caused by CLL, report them to your doctor right away so the cause can be found and treated, if needed.
