Overview

Ewing sarcoma is a type of cancer that begins as a growth of cells in the bones and the soft tissue around the bones. Ewing (Yoo-ing) sarcoma mostly happens in children and young adults, although it can happen at any age.

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

Major advances in the treatment of Ewing sarcoma have improved the outlook for this cancer. Young people diagnosed with Ewing sarcoma are living longer. They sometimes face late effects from the strong treatments. Healthcare professionals often suggest long-term monitoring for side effects after treatment.

Symptoms

Ewing sarcoma signs and symptoms typically start in and around a bone. This cancer most often affects bones in the legs and the pelvis.

When symptoms happen in and around a bone, they might include:

• A lump in the arm, leg, chest or pelvis.
• Bone pain.
• Break in a bone, also called a fracture.
• Pain, swelling or tenderness near the affected area.

Sometimes Ewing sarcoma causes symptoms that affect the whole body. These can include:

• Fever.
• Losing weight without trying.
• Tiredness.

When to see a doctor

Make an appointment with a healthcare professional if you or your child has ongoing signs and symptoms that worry you.
