Complications

Complications of Ewing sarcoma and its treatment include:

• Cancer that spreads (metastasizes). Ewing sarcoma can spread from where it started to other areas, making treatment and recovery more difficult. Ewing sarcoma most often spreads to the lungs and to other bones.
• Long-term treatment side effects. The aggressive treatments needed to control Ewing sarcoma can cause substantial side effects, both in the short and long term. Your health care team can help you manage the side effects that happen during treatment and provide you with a list of side effects to watch for in the years after treatment.
