Ewing's sarcoma is a rare type of cancer that mainly affects children and young adults. It develops in the bones or in the soft tissue around the bones, such as cartilage or the tissue that covers muscle. In rare cases, it can also develop in other parts of the body.
Symptoms of Ewing's sarcoma may vary depending on where the tumor is located. Common symptoms include bone pain, swelling or tenderness around the area of the tumor, and difficulty moving the affected area. Other symptoms may include fever, fatigue, weight loss, and anemia. If the tumor is located near a nerve, numbness or tingling may be experienced.
Diagnosis of Ewing's sarcoma is usually based on a physical exam, imaging tests, and a biopsy. Treatment may include chemotherapy, radiation therapy, or surgery. The prognosis varies depending on the size and location of the tumor, as well as other factors. With early diagnosis and treatment, the outlook for patients with Ewing's sarcoma is generally good.
