Ewing’s sarcoma

A rare malignant form of bone cancer. It arises in a large bone, usually the femur, tibia, humerus, or a pelvic bone, and spreads to other areas at an early stage. The condition is most common in children aged 10–15. An affected bone is painful and tender. It may also become weakened and fracture easily. Other symptoms include weight loss, fever, and anaemia. The sarcoma is diagnosed by X-rays and a biopsy. If cancer is found, the whole skeleton is examined by X-rays and radionuclide scanning, and the lungs viewed by CT scanning, to determine if, and how far, the cancer has spread. Treatment is with radiotherapy and anticancer drugs. If the cancer has not spread, the outlook is good.
