Overview

Ewing (YOO-ing) sarcoma is a rare type of cancer that occurs in bones or in the soft tissue around the bones.

Ewing sarcoma most often begins in the leg bones and in the pelvis, but it can occur in any bone. Less often, it starts in the soft tissues of the chest, abdomen, limbs or other locations.

Ewing sarcoma is more common in children and teenagers, but it can occur at any age.

Major advancements in the treatment of Ewing sarcoma have helped to improve the outlook for people with this cancer. After completion of treatment, lifelong monitoring is recommended to watch for potential late effects of intense chemotherapy and radiation.
