ON THIS PAGE: You will find information about how many people are diagnosed with this type of leukemia each year. You will also learn some general information on surviving the disease. Remember, survival rates depend on several factors. To see other pages, use the menu.
CLL is the most common type of leukemia in adults. This year, an estimated 20,110 people of all ages (12,310 men and 7,800 women) in the United States will be diagnosed with CLL. CLL is more common in older adults. The average age of people diagnosed with CLL is 71. CLL is rare in children.
It is estimated that 4,660 deaths (2,880 men and 1,780 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 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. The 5-year survival rate for people with CLL is 83%.
It is important to remember that statistics on the survival rates for people with CLL are an estimate. The estimate comes from annual data based on the number of people with this cancer in the United States. Also, experts measure the survival statistics every 5 years. So the estimate may not show the results of better diagnosis or treatment available for less than 5 years. People should talk with their doctor if they have questions about this information. Learn more about understanding statistics.
