Final answer:
Ewing's Sarcoma is a rare type of cancer that affects mostly children and young adults, typically involving bones or soft tissue near bones. It presents with pain, swelling, or a lump, and treatment includes surgery, chemotherapy, and radiation.
Step-by-step explanation:
Ewing's Sarcoma is a rare type of cancer that occurs in bones or in the soft tissue around the bones. It most commonly affects children and young adults, particularly those between the ages of 10 and 20. The sarcoma often begins in the long bones of the arms and legs, the pelvis, or the chest wall. However, it can occur in any part of the body. Symptoms may include pain, swelling, or the presence of a lump, and they typically worsen over time.
Treatment for Ewing's Sarcoma typically involves a combination of surgery, chemotherapy, and radiation therapy. The prognosis depends on various factors including the size, location, and extent of the tumor, as well as the patient's age and overall health.
