How Does the Doctor Know if a Child has Ewings Sarcoma?
The doctor will also ask for imaging tests if a lump has been found or other symptoms of a possible tumor have been identified during the exam. The tests might include: • X-rays to locate and identify a potential bone tumor. • Magnetic resonance imaging (MRI) scan, which uses radio waves and strong magnets to create a more detailed image of a potential tumor seen on an X-ray. • Computed tomography (CT or CAT) scan to see if a tumor has spread to the lungs, liver, or lymph nodes. • Bone scan, which uses an injected radioactive material and a special camera to identify potential spots in the skeleton where the cancer may have spread. • Positron emission tomography (PET) scan, which also uses a radioactive material and special camera to identify other spots in the body that may have a tumor. If a potential tumor has been found, the doctor will then ask for a biopsy to confirm the presence of Ewing’s sarcoma. During a biopsy, cells and tissue are removed and then examined in a lab.
