Age- and intercourse-certain cancer of the lung demise costs certainly white never ever cigarette smokers inside CPS-I (1959–1972) and you will CPS-II (1982–2000), stratified of the sex

Cancer of the lung exposure among never ever smokers was also hypothesized so you’re able official site to become high inside the African Us citizens (3) and you will Asians (32) compared to whites.
