Final answer:
Ewing sarcoma predominantly affects kids 10-20 years old with no significant gender preference. X-rays often show an 'onion skin' pattern, and treatment involves surgery, chemotherapy, and potentially radiation.
Step-by-step explanation:
Ewing sarcoma is more common in kids between the ages of 10 and 20 years old. It does not have a significant gender preference, affecting males and females relatively equally. There are certain risk factors associated with Ewing sarcoma, though a family history of the disease has not been definitively linked as one. However, there is more prevalence if there's a history of certain genetic conditions. On an X-ray, Ewing sarcoma typically appears as an area of bone destruction with a layered pattern often described as "onion skin" due to the layering effect. Treatment (tx) for Ewing sarcoma generally involves a combination of surgery, chemotherapy, and sometimes radiation therapy, dependent on the stage and location of the tumor.
