What is Ewing Sarcoma?

Ewing sarcoma is a rare type of cancer that affects bones or the tissue around bones. It is most common in children and young adults but any age group can be diagnosed. It most commonly develops in the pelvis, arms, ribs, femur, tibia and knee. Ewing sarcoma is more prevalent in males than females, but both can be diagnosed.

Causes of Ewing Sarcoma

The exact cause of Ewing sarcoma is unknown. However, as it is predominantly affects older children and teenagers it may well be related to fast growing bones.

Symptoms of Ewing Sarcoma

The symptoms of Ewing sarcoma can vary depending on the location of the tumour.


Common symptoms include:

  • Pain in the affected area that gets progressively worse

  • Swelling and tenderness around the area

  • A high temperature that persists

  • Fatigue

  • Weight loss


In some cases, there might be no symptoms at all. The first suspicion of Ewing could be a broken bone resulting from weakening by the tumour.

These symptoms can be caused by many other things other than Osteosarcoma but if you have any of these symptoms, it is important to see a doctor right away. 

Treatment for Ewing Sarcoma

Ewing sarcoma is a serious disease and treatment plans can be different based on the size, position and stage of the cancer. It is often treated with a combination of surgery and chemotherapy. For some people they may also have radiotherapy.
