Which types of tumors does the Central Brain Tumor Registry include?

The Central Brain Tumor Registry is designed to capture a comprehensive picture of brain tumors, not just those that are malignant. By including benign and borderline tumors alongside malignant tumors, the registry acknowledges the complexities of brain tumors, as well as the impact they can have on patients.

Benign tumors, although not cancerous, can cause significant health issues and may require treatment or surgery depending on their location and size. Borderline tumors, which may exhibit characteristics of both benign and malignant neoplasms, also warrant inclusion for accurate tracking of tumor types and their effects on individuals. This comprehensive approach allows for better research, understanding of treatment outcomes, and resource allocation in oncology.

The other options do not reflect the registry's complete scope. Limiting data collection to only malignant tumors, only metastatic tumors, or only focusing on one specific category would provide an incomplete picture of central nervous system tumors and their epidemiology. Thus, the correct answer reflects the inclusive nature of the registry.
