ON THIS PAGE: You will find information about how many people are diagnosed with 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 14,620 people of all ages (8,140 men and 6,480 women) in the United States will be diagnosed with CLL. It is the most common type of leukemia diagnosed in adults, particularly older adults. CLL is rare in children.
It is estimated that 4,650 deaths (2,830 men and 1,820 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.) The five-year survival rate is the percentage of people who survive at least five years after the cancer found. Overall, the combined five-year survival rate of people with all stages of CLL is about 84%.
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, 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 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. Learn more about understanding statistics.
