bRounded to the nearest 10. Numbers may not add up due to rounding.
cMajor histology grouping estimates are calculated by summing estimates for all included histologies.
dTotal estimate is based on overall estimate, histology-specific estimates may not add up to total.
–Estimated number is less than 50. These cases are included in overall rates.
