ON THIS PAGE: You will find information about how many people are diagnosed with leukemia each year and some general survival information. Remember, survival rates depend on several factors. To see other pages, use the menu on the side of your screen.

This year, an estimated 52,380 people of all ages (30,100 men and boys and 22,280 women and girls) in the United States will be diagnosed with leukemia. About 2% of people diagnosed with leukemia have HCL. An estimated 15,720 people (9,100 men and boys and 6,620 women and girls) in the United States will be diagnosed with CLL this year, though CLL is rare in children. There are no current estimates for how many people develop PLL.

Cancer statistics should be interpreted with caution. Estimates are based on data from thousands of people with this type of cancer in the United States, so the actual risk for a particular individual may be different. It is not possible to tell a person how long he or she will live with B-cell leukemia. Learn more about understanding statistics.

Statistics adapted from the American Cancer Society's publication, Cancer Facts and Figures 2014, and the ACS website.
