Ewing's sarcoma are the most common malignancies of bone tissues in children. There are several types of cells in our bones.
Osteoblasts are the cells that form the matrix of the bone.
Osteoclasts prevent too much bone matrix from accumulating, help bones maintain their proper shape, and control the amount of minerals in the blood. Treatment Treatment and prognosis depends on the subtype and grade of the tumor. Intermediate grade tumors are treated with both surgery and chemotherapy. Osteosarcomas do not respond to radiation therapy. When possible, the limb is spared by removing the tumor and replacing the bone with a bone graft or metal rod.
