ON THIS PAGE: You will find information about how many people learn they have leukemia each year. Remember, survival rates depend on several factors. To see other pages in this guide, use the colored boxes on the right side of your screen, or click “Next” at the bottom.

This year, an estimated 52,380 people of all ages (30,100 males and 22,280 females) in the United States will be diagnosed with leukemia. HCL accounts for about 2% of all leukemia diagnoses. An estimated 15,720 people (9,100 males and 6,620 females) in the United States will be diagnosed with CLL this year. 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, but the actual risk for a particular individual may differ. 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.
