Key Statistics for Chronic Lymphocytic Leukemia
The American Cancer Society's estimates for leukemia in the United States for 2024 are:
- About 62,770 new cases of leukemia and about 23,670 deaths from leukemia (all kinds)
- About 20,700 new cases of chronic lymphocytic leukemia (CLL)
- About 4,440 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 1 in 175 (0.57%). The risk is slightly higher in men than in women.
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 is extremely rare in children.
