Mom has recently become involved with the relatively newly formed Lung Cancer Circle of Hope. While this New York Times article may not have a particularly well-presented and overarching thesis (unlike, say, the piece mentioned here), it's woth a read:
"If 80 percent or so stem from smoking, that leaves about 36,000 cases and 30,000 deaths a year that are not related to smoking. That puts non-smoking-related lung cancer in the same league with colorectal, prostate and breast cancer. If we wiped out smoking, lung cancer would still be the No. 3 cancer killer of Americans."
