Ewing's Family of Tumors

Risk Factors

Only about 1-2 percent of all childhood bone tumors are EFTs. About 250 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.
