Key Statistics for Chronic Lymphocytic Leukemia
The American Cancer Society's estimates for chronic lymphocytic leukemia (CLL) in the United States for 2024 are:
- About 20,700 new cases of CLL
- About 4,440 deaths from CLL
CLL accounts for about 1 in 3 new cases of leukemia in the US, and about 1% of cancers overall.
CLL is slightly more common among men than women, but the average lifetime risk of getting CLL for both sexes is about ½ of 1%.
CLL mainly affects older adults. The average age of people when they are diagnosed is around 70 years. It's rarely seen in people under age 40, and it's extremely rare in children.
