Doctor's Notes on Ewing Sarcoma

Ewing sarcoma is a rare tumor type (cancer) that forms from abnormal bone or soft tissue cells and is most common in adolescents and young adults. Signs and symptoms include pain and/or swelling most often in the legs, arms, chest, back or pelvis; a lump or bump that is somewhat soft and warm may be found in the same areas. Also, the patient may have a fever but no clear source or reason for it and in some people, a bone fracture may develop for no good reason (until the tumor is found and diagnosed).

Although researchers have found some chromosome changes that may lead to Ewing sarcoma development, they are not inherited and develop after birth for unknown reasons. The exact cause of Ewing sarcoma is not known.
