What causes Desmoid tumors?

No one knows the exact cause of Desmoid tumors. Researchers have found that Desmoid tumors may occur in patients who have a history of polyposis coli, a hereditary colon cancer syndrome.

What are the symptoms of a Desmoid tumor?

Because Desmoid tumors affect tissue that is elastic and easily moved, a tumor may exist for a long time before being discovered, growing large and pushing aside surrounding tissue.

Each child may experience symptoms differently, but here's a list of the most common symptoms of Desmoid tumors:

  • a painless swelling or lump
  • pain or soreness caused by compressed nerves or muscles
  • pain and obstruction of the bowels
  • limping or other difficulty using the legs, feet, arms or hands

The symptoms of Desmoid tumors may resemble other conditions or medical problems, so you should always talk to you child's doctor for a diagnosis.
