[Prevention of lung cancer through smoking control activities in Japan].

Three kinds of smoking cessation programs have been developed by the Osaka Cancer Prevention and Detection Center. The first program is "Smoking Quit Contest," in which self-help materials are mailed to applicants and prizes are given by lot to those who succeed in quitting. The second program is a "Smokebusters" smoking cessation program designed for outpatients. The third program is designed for people undergoing screening during routine health check-ups, which are widely conducted in communities and workplace in Japan. To reduce lung cancer mortality in Japan, smoking cessation programs such as those described here should be widely implemented and the prevalence of smoking among men in Japan should be reduced at least to the levels in the U.S. and in western Europe.
