What are the causes of Ewing sarcoma?

The causes of Ewing sarcoma remain unknown. Although Ewing sarcoma arises from specific types of cells, it doesn’t appear to be inherited.

But some statistics show that genetic exchange between chromosomes can cause cells to become cancerous. About 85% cases of Ewing sarcoma are the result of a translocation between chromosomes 11 and 22, which fuses the EWS gene f chromosome 22 to the FL 11 gene of chromosome 11, according to Wikipedia.
