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 on the side of your screen.
CLL is the most common type of leukemia in adults. This year, an estimated 18,960 people of all ages (10,380 men and 8,130 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 82%.
It is important to remember that statistics on how many people survive this type of cancer are an estimate. The estimate comes from data based on thousands of people with this cancer in the United States each year. So, your own risk may be different. Doctors cannot say for sure how long anyone will live with CLL. Also, experts measure the survival statistics every 5 years. This means that the estimate may not show the results of better diagnosis or treatment available for less than 5 years. Learn more about understanding statistics.
