  1. a. Rates are per 100,000 and are age-adjusted to the 2017 GCC population (AIRGCC) and 2000 US standard population (AIRUS)
  2. -- Average annual age-adjusted incidence rates with 95% confidence intervals are not presented when fewer than 5 cases were reported for the specific category
  3. Tumor categories with zero cases per age group were excluded from the above table
