What is Ewing sarcoma?

Ewing sarcoma is a cancer that arises from bone or the soft tissue around bone. It most commonly occurs in the spine, pelvis, chest, arms or legs. It sometimes will spread to the lungs.

Symptoms and diagnosis

Advanced treatment options

Treatment for Ewing sarcoma can include one or all of the following:

  • Chemotherapy
