This database provides cancer incidence data, crude rates, and age-adjusted rates by race for the United States and most states. It includes the leading cancers reported by the CDC.  Crude rates indicate the number of cases reported each calendar year per 100,000 population. Age-adjusted rates are weighted averages of the age-specific (crude) rates, where the weights are the proportions of persons in the corresponding age groups of a standard million population. See CDC for more details.
