Risk Factors
Only about 5 percent of all childhood bone tumors are EFTs. About 150 children and adolescents are diagnosed with a Ewing's tumor in the United Sates each year.
Certain risk factors may increase a person's chance of developing EFTs. These include:
- Race: For unknown reasons, Ewing's occurs most frequently
in the white population and is rare among African Americans and Asian Americans.
- Sex: Ewing's is slightly more common in boys than
girls.
- Age: About 27 percent of all Ewing's cases are diagnosed in children younger than 10 years old. The majority of cases -- 64 percent -- occur in children between the ages of 10 and 20. Ewing's is rare among adults, and is almost never seen in anyone over the age of 30.
