Leukemia - Chronic Lymphocytic - CLL: Statistics

This section has been reviewed and approved by the Cancer.Net Editorial Board, 07/2014

ON THIS PAGE: You will find information about how many people learn they have this type of 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 15,720 people of all ages (9,100 men and 6,620 women) in the United States will be diagnosed with CLL. Children are almost never diagnosed with CLL, but it is the most common type of leukemia diagnosed in adults. It is estimated that 4,600 deaths (2,800 men and 1,800 women) from CLL will occur this year.

The survival rate for people with CLL varies widely according to the stage of the disease (see Stages) and can range from about one year to more than 20 to 30 years. The five-year survival rate is the percentage of people who survive at least five years after the cancer is detected, excluding those who die from other diseases. The five-year survival rate of people with CLL is about 79%.

Cancer survival statistics should be interpreted with caution. These estimates are based on data from thousands of people with this type of cancer in the United States each year, 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 CLL. Because the survival statistics are measured in five-year intervals, they may not reflect recent advances made in the treatment or diagnosis of this cancer.
