* New cases diagnosed per 100,000 persons, age adjusted to the 2000 U.S. standard population.
† New cases diagnosed.
§ Cancer incidence data were compiled from cancer registries that met the data quality criteria for all invasive cancer sites combined, representing approximately 99% of the U.S. population. (Data from Nevada did not meet U.S. Cancer Statistics publication criteria for 2010–2014.)
¶ Ethnicity is not mutually exclusive from race.
** Only includes microscopically confirmed cases; excludes cases identified only through death certificate or autopsy report.
†† Localized: cancer that is confined to the primary site; regional: cancer that has spread directly beyond the primary site or to regional lymph nodes; distant: cancer that has spread to other organs.
