Which type of edit compares data from the abstract with outside sources in the central registry database?

The correct answer is the type of edit that compares data from the abstract with outside sources in the central registry database. This is known as an inter-database edit. Inter-database edits are specifically designed to validate the data by cross-referencing it with information from other databases, which can help ensure accuracy and completeness.

In the context of tumor registry operations, utilizing external sources increases the reliability of the data collected, which is critical for tracking cancer incidence, outcomes, and trends. By performing this type of edit, registrars can identify discrepancies and potential errors that may arise from incomplete or inaccurate data submissions.

Other types of edits, such as range edits and inter-field edits, serve different purposes. Range edits typically check if the data falls within a predefined range or meets predetermined criteria, while inter-field edits compare related fields within the same abstract for consistency. However, they do not offer the comprehensive validation that inter-database edits provide by bringing in external data for comparison.
