Which registry collects data on all newly diagnosed cancer cases in a defined geographic area for public health and epidemiology?

• A. Hospital-based cancer registries
• B. Specialty cancer registries
• C. Population-based cancer registries
• D. National cancer registries

Answer: (C)

At the heart of this question is the ability to measure cancer occurrence in a defined population. Population-based cancer registries are designed to capture every new cancer case diagnosed within a specific geographic area, such as a city, county, state, or country. This comprehensive approach allows researchers and public health officials to calculate accurate incidence rates, examine trends over time, and analyze data by age, sex, race, and other factors. They gather information from multiple sources—hospitals, pathology labs, physicians, and even death certificates—and follow individuals to determine outcomes like survival. This broad, population-wide coverage is essential for surveillance, planning, and evaluating cancer control efforts, making it the best type for the described purpose. Hospital-based registries focus on patients treated at particular institutions, specialty registries target specific cancer types or groups, and national registries can be population-based but the defining feature here is the complete capture within a defined geographic area.
