What is Ewing's Sarcoma?

Ewing's sarcoma is a cancer that occurs primarily in the bone or soft tissue. Ewing's sarcoma can occur in any bone, but it most often it is found in the long bones such as the femur (thigh), tibia (shin), or humerus (upper arm). It can involve the muscle and the soft tissues around the tumor as well. Ewing's 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.

Who Develops Ewing's Sarcoma?

Ewing's sarcoma is a very rare cancer in adults. However, Ewing's sarcoma accounts for about one to two percent of childhood cancers.

Information about Ewing's sarcoma in childhood can be found at Lucile Packard Children's Hospital.
