There is no way to know for sure if you’re going to get Ewing sarcoma. And there is no known way to prevent it.
Certain factors can make you more likely to get cancer than another person. These are called risk factors. There have not been any lifestyle (such as smoking) or inherited risk factors that have been directly linked to Ewing sarcoma. However, there are a few general risk factors for getting Ewing sarcoma.
Ewing sarcoma is most common in people who are between 10 and 20 years old.
Ewing sarcoma is more common in white people than in black people or other ethnic groups.
Ewing sarcoma affects males slightly more frequently than females.
It is important to keep in mind that risk factors can't be used to tell for sure whether or not you will get cancer. You may have all of these general risk factors and not get Ewing sarcoma. Or you may have none of these factors and get this type of cancer.
