  • aAge-standardized to the 2000 U.S. standard population by 5-year age groups and expressed per million person-years.

  • bRace/ethnicity categories are mutually exclusive. Unknown race/ethnicity cancers do not have incidence rates or trends given a lack of denominator (population size) estimate for this group.
