Approved by the Cancer.Net Editorial Board, 07/2015

ON THIS PAGE: You will find information about how many children are diagnosed with this type of cancer 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.

ALL is the most common type of childhood cancer. Approximately 3 of 4 children who are diagnosed with leukemia are diagnosed with ALL. It is most common in children younger than 5, with most cases occurring between the ages of 2 and 4.

The 5-year survival rate tells you what percent of children live at least 5 years after the cancer is found. Percent means how many out of 100. The 5-year survival rate for children with ALL has greatly improved over time and is now 90%. 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 children with ALL are an estimate. The estimate comes from annual data based on the number of children 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.
