I think John Wayne was a lung cancer survivor (had part of one removed, as I recall), but died of stomach cancer.

I just remember those commercials he taped to be played after his death about how smoking was the reason he died. Or am I remembering this wrong (not unheard of, LOL!)?

John Wayne did have part of his lung removed right before filming "Rooster Cogburn" with Katherine Hepburn.
