Ewing Sarcoma

What is Ewing sarcoma?

Ewing sarcoma is a cancer that occurs primarily in the bone or soft tissue. Ewing sarcoma can occur in any bone, but is most often found in the extremities and can involve muscle and the soft tissues around the tumor site. Ewing sarcoma cells can also spread (metastasize) to other areas of the body including the bone marrow, lungs, kidneys, heart, adrenal gland, and other soft tissues.

Ewing sarcoma accounts for about 2 to 3 percent of childhood cancers. About 150 children and adolescents are diagnosed with Ewing sarcoma each year in the US. It is the second most common malignant bone tumor in children and adolescents. Ewing sarcoma most often occurs in children between the ages of ten and 20. The number of males affected is slightly higher than the number of females.
