Leukemia - Acute Lymphoblastic - ALL - Childhood: Statistics

Approved by the Cancer.Net Editorial Board, 03/2020

ON THIS PAGE: You will find information about the number of children and teens who are diagnosed with ALL each year. You will also read general information on surviving the disease. Remember, survival rates depend on several factors. Use the menu to see other pages.

ALL is the most common type of childhood cancer. Approximately 3 of 4 children and teenagers diagnosed with leukemia are diagnosed with ALL. Most cases occur between age 2 and 5. However, an estimated 400 people ages 15 to 19 in the United States will be diagnosed with the disease this year. It is less common in girls than boys.

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 under age 20 with ALL has greatly improved over time and is now 89%. For children diagnosed with acute leukemia, those who remain free from the disease after 5 years are generally considered “cured” because it is rare for acute leukemia to recur after this amount of time. 

It is important to remember that statistics on the survival rates for people with ALL are an estimate. The estimate comes from annual data based on the number of children and teens 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. Talk with your child’s doctor if you have any questions about this information. Learn more about understanding statistics.
