Sarcoma's are rare tumors affecting the bone, muscles and ligaments. Ewing's sarcoma is a malignant tumor of the bones that occurs most commonly in adolescence and early adulthood. It constitutes somewhere between 10 and 15% of all sarcomas of the bone. When the disease begins below the elbow or below the mid-calf, there is about an 80% chance of surviving

five years. The disease frequently spreads or metastasizes to other parts of the body, the areas most at risk include the lungs, bones and bone marrow.

Causes of Ewing's Sarcoma


The exact cause of the disease is unknown. There are some chromosomal changes associated with it at times.

Signs and Symptoms of Ewing's Sarcoma


Like other tumors of the bone, Ewing's sarcoma produces a mass or enlargement of the affected bone. Weakening of the involved bone may occasionally lead to unexplained fractures. If metastatic disease is present, symptoms occur which are referable to the region involved. Lung involvement may produce shortness of breath, cough or chest pain. If the bone marrow is diffusely involved, there may be anemia. Symptoms may include pallor, weakness, easy bruising and bleeding.
