    It is thought that Ewing sarcoma is caused by a genetic problem.

    Risk Factors

    Ewing sarcoma is more common in Caucasians, teenagers, and males.


    Symptoms may include:
    • Pain, redness, and swelling surrounding the tumor
    • Difficulty moving around
    • Fever
    • Weight loss and reduced appetite
    • Fatigue
    • Loss of bladder control
    • Numbness, tingling, and paralysis
    • Difficulty breathing
    Ewing sarcoma can also weaken the bone leading to unexplained fracture of the bone.


    You will be asked 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:

    Chemotherapy and Radiation Therapy

    Chemotherapy is the use of drugs to kill cancer cells. Chemotherapy may be used along with radiation therapy . This is the use of high-energy x-rays to kill cancer cells.


    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 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.

    Rehabilitation Therapy

    Physical and occupational therapy will help your child manage physical challenges including:
    • Re-learnig how to do daily tasks
    • Resuming physical activity
    • Learning how to use a prosthesis
    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.
