A Cancer Registry Abstractor is a healthcare professional who collects, analyzes, and maintains cancer patient data for research, treatment, and registry purposes. They review medical records, pathology reports, and other documents to ensure accurate coding and classification of cancer diagnoses and treatments. This data helps in understanding cancer trends, improving patient care, and meeting regulatory requirements. Abstractors typically work in hospitals, cancer centers, or public health organizations and must have knowledge of medical terminology, coding systems, and cancer treatment guidelines.
