We are seeking a highly experienced Certified Tumor Registrar (CTR) to join our team as a part-time domain expert and process advisor. This long-term collaboration aims to deepen our understanding of oncology registry workflows, data abstraction standards, and interoperability processes across population-based and hospital-based cancer data systems. The role is ideal for a senior registrar who enjoys sharing expertise, advising on best practices, and helping non-registry professionals translate complex oncology data workflows into digital, interoperable systems.
