United States Cancer Statistics (USCS) contains data from which sources?

• A. NPCR and SEER
• B. NPCR
• C. SEER
• D. All data sources contributed to USCS

Answer: (A)

USCS compiles national cancer statistics from two main population-based registry systems: NPCR and SEER. NPCR collects cancer incidence data from state cancer registries, covering the vast majority of the U.S. population. SEER gathers high-quality incidence and survival data from selected geographic areas. By combining data from both programs, USCS provides a comprehensive national picture as well as state-level detail. Therefore, the sources are these two registries; it isn’t based on a single source or “all data sources.”
