__________ Collects cancer Data.

A Health Information Manager oversees the overall management of patient health records and information systems, not the specialized collection of cancer-specific data.

A Cancer Registrar collects and maintains data on cancer diagnoses, treatment, and outcomes within a facility, contributing to national cancer databases such as those managed by the American Cancer Society and the National Cancer Institute. This role requires knowledge of cancer staging, pathology reports, and registry standards. The data collected is used for research, public health reporting, and quality improvement.

A Coder assigns diagnostic and procedural codes to clinical documentation for billing and data retrieval, which is a separate function from cancer registry work.
