Ewing Sarcoma Family Tumors are best described as which?

• A. A single tumor in one tissue
• B. A benign bone growth
• C. Group of tumors that attack separate tissues
• D. A muscle strain

Answer: (C)

Ewing Sarcoma Family Tumors are a group of related malignant tumors that can arise in bone or soft tissue at various sites. They share a common genetic feature and behave as a family rather than a single tumor confined to one tissue. Because they are malignant and can involve different tissues, the best description is a group of tumors that affect separate tissues, not a benign growth or a muscle strain.
