Factors that increase the risk of Ewing sarcoma include:
- Race: Caucasians are more likely to get this type of cancer than people who are African American or Asian
- Age: More common among teenagers
Symptoms may include:
- Pain, redness, and swelling surrounding the tumor
- Difficulty moving around

will help to replace smaller areas of missing bone. An artificial limb may be needed if larger areas of the bone are affected. There are special types of artificial limbs that expand as the bone grows. Several surgeries may be needed to make sure the limb functions properly.
Stem Cell Transplant
Stem cells grow into blood cells and platelets. The cancer and the treatments can damage stem cells which makes it difficult for the body to produce healthy blood cells. A
stem cell transplant
can help replace the damaged stem cells. The new cells are injected into a vein, and travel to the bone cavities where they will grow and begin work.
Physical and occupational therapy will help your child manage physical challenges including:
