classify_icd10(icd10, cancer_type = "big")
#> [1] "103" "110" "126" "126" "104"
classify_icd10(icd10, cancer_type = "small")
#> [1] "10" "21" "59" "59" "11"
classify_icd10(icd10, cancer_type = "system")
#> [1] "202" "203" "211" "202" "202"
classify_icd10(icd10, cancer_type = "gco")
#> [1] "306" "315" "337" "338" "307"
