## Leukemia - B-cell Prolymphocytic Leukemia and Hairy Cell Leukemia - Statistics [1]

**ON THIS PAGE:** You will find information about how many people are diagnosed with 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.

This year, an estimated 60,140 people of all ages (34,090 men and boys and 26,050 women and girls) in the United States will be diagnosed with leukemia.

CLL is the most common type of adult leukemia. An estimated 18,960 people (10,380 men and boys and 8,130 women and girls) in the United States will be diagnosed with CLL this year, though 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. There are no current estimates for how many people develop PLL. HCL accounts for about 2% of all leukemia diagnoses.

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 leukemia are an estimate. The estimate comes from data based on thousands of people with these types of leukemia in the United States each year. So, your own risk may be different. Doctors cannot say for sure how long anyone will live with leukemia. 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 [3].
