Counts pertain to 99.2% of the US population covered by eligible cancer registries. Data from 1 central cancer registry are not included. Percentages may not add to 100% because of rounding.
Rates are per 100,000 persons and age-adjusted to the 2000 US standard population (19 age groups; Census P25-1130), except age-specific rates, which were not age-adjusted.
Ninety-five percent confidence intervals (CIs) were calculated using the Tiwari modification.
Race and ethnicity are not mutually exclusive.
Indicates that rates could not be calculated or not applicable.
Indicates that percentage microscopic confirmation includes positive histology, positive exfoliative cytology; no positive histology, and positive microscopic confirm; method not specified.
Indicates that the count was <16 for 2004–2007 and was suppressed or that the number was complementarily suppressed for 2004–2007 to ensure patient privacy and confidentiality.
