Approved by the Cancer.Net Editorial Board, 08/2015

ON THIS PAGE: You will find information about how many children are diagnosed with medulloblastoma 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.

About 18% of childhood brain tumors are medulloblastoma. Approximately 70% of all cases occur in children under age 10.

 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.  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%. 

It is important to remember that statistics on how many children survive medulloblastoma are an estimate. The estimate comes from data based on the children with this type of tumor in the United States each year. So, your own child’s risk may be different. Doctors cannot say for sure how long any child will live with medulloblastoma. 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.
