In Ewing sarcoma, which age group is most frequently affected?

Ewing sarcoma primarily affects children and adolescents, generally between the ages of 10 and 20. This malignant bone tumor is known for its association with the long bones, pelvic bones, and occasionally soft tissues. The peak incidence occurs during the growth spurts of this age group, making them the most frequently affected demographic. Understanding the age-related patterns of Ewing sarcoma is essential for early diagnosis and intervention, as the prognosis improves significantly with timely treatment.

As the other choices represent age groups outside of this primary demographic, they do not align with the well-established epidemiological data surrounding Ewing sarcoma.
