Each year, about 225 children and teenagers in the United States are diagnosed with a Ewing tumor each year. EFT makes up about 1% of all childhood cancers. The five-year survival rate (the percentage of people who survive at least five years after the tumor is detected, excluding those who die from other diseases) of people with EFT is about 70% for a localized tumor (a tumor that has not spread). If the tumor has metastasized (spread) at the time of diagnosis, the five-year survival rate is about 15% to 30%. The survival rate is slightly higher for patients whose tumor has spread to the lungs only, compared with those whose tumor has spread to the lungs and the bones.

Cancer survival statistics should be interpreted with caution. These estimates are based on data from thousands of people with this type of tumor in the United States, 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 EFT. Because the survival statistics are measured in five-year intervals, they may not represent advances made in the treatment or diagnosis of EFT. Learn more about understanding statistics [2].
