Ewing sarcoma is a type of cancer that occurs in the bone or soft tissue. Areas that are commonly affected include the pelvis, thigh, lower leg, upper arm, and chest wall. Prognosis depends on the location of the tumor and whether it has spread to other parts of the body.

It is thought that Ewing sarcoma is caused by a genetic problem.
Factors that increase the risk of Ewing sarcoma include:
Symptoms may include:
Ewing sarcoma can also weaken the bone leading to unexplained fracture of the bone.
The doctor will ask about your child’s symptoms and medical history. A physical exam will also be done. Ewing may be suspected if a bone breaks after a minor injury. A sample of the tissue will be removed and sent for examination, also called a biopsy.
Images of the body may be taken to locate the tumor and determine if it has spread to other tissues. Images may be taken with:
Your child will work with a team of doctors. Talk with the team to determine the best treatment options for your child. These options include:
Surgery may be used to remove the tumor.
Surgery may also be done to rebuild the affected bone. A bone graft 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 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:
Other therapists or specialists will also help your child through emotional challenges of illness and treatment.
There is no known way to prevent this condition.
