The Glossary for Registrars is an interactive web-based tool with over 5,000 terms defined for cancer registrars. Use the glossary to find definitions for anatomy terms, cancer-related terms, common diseases (and not-so-common diseases), physiology terms, surgical procedures, other treatment procedures, and much more.

The glossary can be accessed directly from the SEER website or accessed by clicking on linked terms in the Hematopoietic database and SEER*Rx.

The glossary is a work in progress. New terms will be added and the tool will be updated quarterly.

If you have questions or comments about the glossary, please submit them to Ask a SEER Registrar and choose “Glossary for Registrars.”
