Glossary, in plain language.

Medical visits come with a vocabulary of their own. This glossary gathers every term defined across the cancer guides on this site, so you can look one up quickly and see which guide explains it in context.

Definitions are written for patients and families and are deliberately brief. A term can mean slightly different things in different situations, so ask your care team how it applies to you. Each entry links to the guide or guides where it appears.
