How is Ewings sarcoma staged?
Once Ewing’s sarcoma has been diagnosed, the tumor is staged. This process indicates how far the tumor has spread from its original location. The stage of a tumor suggests which form of treatment is most appropriate, and gives some indication as to prognosis. A Ewing sarcoma may be localized, meaning it has not spread beyond the bone where it arose or beyond nearby tissues, or metastatic, meaning it has spread to lungs, bones other than the bone that the tumor originated in, or to other organs or structures of the body.
