What is Ewing's sarcoma?
A child with Ewing's sarcoma has a rare type of primary bone cancer. In primary bone cancer, abnormal bone cells multiply out of control, form tumors, and spread to other parts of the body. Ewing's sarcoma is most common in children between 4 and 15 years old. When Ewing's sarcoma grows, it destroys normal bone. When the bone becomes too weak, a pathologic fracture can occur.

What are the symptoms of Ewing's sarcoma?

How does the doctor treat Ewing's sarcoma?
Treatment for Ewing's sarcoma may include surgery, radiation therapy, and chemotherapy.
