Collectively grouped under the Ewing sarcoma family of tumors, Ewing's sarcoma is the second most common form of bone cancer, which is commonly seen in children and adolescents. Very rarely is it experienced in adults above the age of 30.
Typically forming in the bones of the chest, pelvis, head, back or trunk and in the long bones of the arms and legs, Ewing's sarcoma is believed to originate in certain kinds of primitive cells. When it begins to affect similar kind of cells found outside the bone, it is usually called an extraosseous Ewing's sarcoma.
1. Similar to all types of Ewing tumors, Ewing's sarcoma is generally caused by an alteration in a certain cell compelling a gene named EWS found on chromosome no. 22 to move over to a DNA section on any one of the surrounding chromosomes resulting in the activation of the EWS gene.
2. While it is not a hereditary condition, it usually occurs after childbirth, but no substantial evidence has been found as to why it happens so.
2. Swelling accompanied by joint immobility
Because the symptoms of Ewing's sarcoma can hardly be distinguished from symptoms caused by other infections or injuries, an early diagnosis is absolutely necessary for a successive treatment. If you wish to discuss about any specific problem, you can consult an oncologist and ask a free question.
