Every year roughly 20,000 people who have never touched a cigarette are diagnosed with lung cancer, and women are particularly at risk, for reasons no one understands. Recent research has suggested that women who don't smoke are two to three times more likely than nonsmoking men to develop lung cancer. Research also suggests that women may be more vulnerable than men to the carcinogenic effects of smoking according to in some studies, women who smoked have been shown to be roughly twice as likely to develop lung cancer as men who smoked.
