ON THIS PAGE: You will find information about the number of children who are diagnosed with medulloblastoma 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.
Between 250 and 500 children are diagnosed with medulloblastoma each year. About 18% to 20% of childhood brain tumors are medulloblastoma. More than 70% of all medulloblastomas occur in children younger than 10. The chance of developing medulloblastoma lessens with age. Medulloblastoma can occur in adults, but it is less common.
The 5-year survival rate tells you what percent of children live at least 5 years after the tumor is found. Percent means how many out of 100. For children with medulloblastoma, the survival rate depends on several factors, including the risk level for this disease and the child’s age when diagnosed.
Overall, the 5-year survival rate for children with average-risk disease is 70% to 80%. For children with high-risk disease, the rate is about 60% to 65%. For infants with localized disease, the rate is between 30% and 50%. Learn more about risk level in the Stages section.
It is important to remember that statistics on the survival rates for children with medulloblastoma are an estimate. The estimate comes from annual data based on the number of children with this type of tumor 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.
