SEER Cause of Death Recode

For reporting of cancer mortality data, SEER has defined major site groups based on the International Classification of Diseases versions 6-10 for year of death 1950+ and 8-10 for year of death 1969+. The site groupings are defined consistently over time to facilitate reporting of long term trends.
