What is Ewing Sarcoma?

What Causes Ewing Sarcoma?

The exact cause is unknown, although a characteristic genetic change is found in many tumour cells. It commonly affects the pelvis, thigh or shin bones and can also arise in soft tissue. It is not contagious, and sports are not considered a cause.

Symptoms

• Bone pain that gradually increases over weeks and does not settle with rest
• Swelling, warmth or tenderness over the painful area
• Restricted movement or a limp when the lesion is near a joint
• Fever, fatigue or unintentional weight loss

Frequently Asked Questions

How is Ewing sarcoma diagnosed?

After examination, X-rays, MRI and chest imaging help assess the location and spread. A biopsy with pathology and molecular testing confirms the diagnosis. Treatment is usually planned by paediatric oncology, orthopaedics and radiation oncology and may combine chemotherapy, surgery and radiotherapy when needed.
