What Are the Key Statistics for Chronic Lymphocytic Leukemia?
The American Cancer Society's estimates for leukemia in the United States for 2017 are:
- About 62,130 new cases of leukemia and about 24,500 deaths from leukemia (all kinds)
- About 20,110 new cases of chronic lymphocytic leukemia (CLL)
- About 4,660 deaths from CLL
CLL accounts for about one-quarter of the new cases of leukemia. The average person's lifetime risk of getting CLL is about ½ of 1% (about 1 in 200). The risk is slightly higher in men than in women.
CLL mainly affects older adults. The average age at the time of diagnosis is around 71 years. It is rarely seen in people under age 40, and is extremely rare in children.
