-The values of SEER site recode variables are based on the primary site and histology data fields submitted to SEER by the
-registries. The site recode variables define the major cancer site/histology groups that are commonly used in the reporting of
-cancer incidence data. For example, there is a section of the SEER Cancer Statistics Review for each major site corresponding to
-groupings in a site recode variable. The site recode variables are added to SEER databases as a convenience for researchers.
+The API supports three algorithms for recoding site: SEER site recode ("seer"), International Classification of Childhood Cancer Site Recode ("iccc"), 
+and Adolescents and Young Adults Site Recode ("aya"). The values of SEER site recode variables are based on the primary site, histology and
