Childhood Soft Tissue Sarcoma Treatment (PDQ®): Treatment - Patient Information [NCI] - General Information About Childhood Soft Tissue Sarcoma

continued...

Having certain diseases and inherited disorders can increase the risk of childhood soft tissue sarcoma.

Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. People who think they may be at risk should discuss this with their doctor. Risk factors for childhood soft tissue sarcoma include having the following inherited disorders:

  • Li-Fraumeni syndrome.
  • Neurofibromatosis type 1 (NF1).
  • Familial adenomatous polyposis (FAP).

Other risk factors include the following:

  • Having AIDS (acquired immune deficiency syndrome) and Epstein-Barr virus infection.
  • Having retinoblastoma in both eyes.
  • Past treatment with radiation therapy.

The most common sign of childhood soft tissue sarcoma is a painless lump or swelling in soft tissues of the body.

A sarcoma may appear as a painless lump under the skin, often on an arm, a leg, or the trunk. There may be no other symptoms at first. As the sarcoma grows larger and presses on nearby organs, nerves, muscles, or blood vessels, symptoms may occur, including pain or weakness.

Other conditions may cause the same symptoms that soft tissue sarcomas do. A doctor should be consulted if any of these problems occur.

Diagnostic tests and a biopsy are used to detect (find) and diagnose childhood soft tissue sarcoma.

The following tests and procedures may be used:

  • Physical exam and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient's health habits and past illnesses and treatments will also be taken.
  • X-rays: An x-ray is a type of energy beam that can go through the body onto film, making pictures of areas inside the body. A series of x-rays may be done to check the lump or painful area.
  • MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).
