Quite often a child’s regular doctor may have already performed some type of x-ray; such exams are often repeated by the specialist. If a bone tumor is suspected, it is important that the child is diagnosed and treated by a team experienced in dealing with children with cancer.
In patients with Ewing Sarcoma, 10% to 30% have metastatic disease at the time of diagnosis, meaning the cancer has spread to other areas. Staging the disease—determining how far it has spread—is very important because it helps the healthcare team make the best, most informed decisions about treatment.
Researchers currently DO NOT know what causes Ewing’s sarcomas. However, they do know that it is not associated with any other cancers and there is no additional risk among families in which a single person has Ewing Sarcoma.
Only a few risk factors for Ewing sarcomas are known for sure. Ewing sarcomas occur mostly in Caucasian and Hispanic children. Caucasian and Hispanic or Latino children are about 9 times more likely to develop Ewing sarcoma compared to African American children. Ewing sarcomas are rare in Chinese and Japanese children. More boys than girls develop Ewing sarcoma.
