Y1 - 2010 N1 - T2 - Kuerer's Breast Surgical Oncology AB - Staging is the classification used to define the risk of cancer recurrence and mortality. Cancer staging is useful for assessing prognosis and defining care for individuals and for defining the changes in cancer incidence and outcome for populations. A number of classifications systems for defining the extent or "stage" of cancer are used worldwide, each with its own historical basis and purpose. Three systems are used widely in the United States: the Extent of Disease (EOD) system used by the National Cancer Institute Surveillance, Epidemiology, and End Results Program (SEER); the Summary Stage system used primarily by state cancer registries; and the Tumor, Node, Metastases (TNM) system. The EOD and Summary Stage systems are used by population registries primarily for the purpose of population cancer surveillance. These systems generally do not change over time, allowing evaluation of temporal changes in cancer incidence and presentation.
