Cancer Staging. Staging is the process of finding out how much cancer is in a personâs body and where itâs located. Itâs how the doctor determines the stage of a personâs cancer. For most types of cancer, doctors use staging information to help plan treatment and to predict a personâs outlook (prognosis). Although each personâs situation is different, cancers with the same stage tend to have similar outlooks and are often treated the same way.
