What Is Leukemia - Chronic Lymphocytic (CLL)? TOPICS

What are the key statistics for chronic lymphocytic leukemia?

The American Cancer Society's estimates for leukemia in the United States for 2015 are:

  • About 54,270 new cases of leukemia and about 24,450 deaths from leukemia (all kinds)
  • About 14,620 new cases of chronic lymphocytic leukemia (CLL)
  • About 4,650 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.
