What term describes patient identification information and detailed medical histories processed by cancer registries?

• A. Confidential health information
• B. Personal data
• C. Public health data
• D. De-identified information

Answer: (A)

The patient identification information and detailed medical histories handled by cancer registries are best described as confidential health information. This term emphasizes the privacy and protection required for sensitive health data, which registries keep restricted to authorized personnel and use only for legitimate purposes like tracking cancer cases and follow-up. While registries may link records using identifiers, the information is safeguarded to maintain confidentiality. De-identified information refers to data stripped of identifying details for research or public reporting, which is not the same as the identifiable data processed in routine registry operations. Public health data describes non-identifying, aggregate data, not the identifiable records in question, and personal data is a broader term that doesn’t specifically highlight the health-privacy context.
