## Medulloblastoma - Childhood - Statistics [1]

**ON THIS PAGE**: You will find information about how many children learn they have medulloblastoma each year and some general survival information. Remember, survival rates depend on several factors. To see other pages, use the menu on the side of your screen.

About 18% of childhood CNS tumors are medulloblastoma. The overall five-year survival rate is the percentage of people who survive at least five years after the tumor is detected excluding those who die from other diseases. For children with medulloblastoma, this depends on several factors, including the risk level for this disease and the child’s age when diagnosed. Overall, the five-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%. If the child is an infant and the disease is localized, the survival rate is between 30% and 50%.

Survival statistics should be interpreted with caution. These estimates are based on data from thousands of children with this type of tumor, but the actual risk for a particular individual may differ. It is not possible to tell a person how long he or she will live with medulloblastoma. Because the survival statistics are measured in five-year intervals, they may not represent advances made in the treatment or diagnosis of this cancer. Learn more about understanding statistics [3].
