LUNG CANCER VOL. 44 181 keino- in a particular occupational iip affects the chances of developing rcancer and likewise how cigarette Poking modifies these chances. Conclusion The data in this study constitute still nother link in the chain of evidence Connecting lung cancer with cigarette 'inoking, evidence, which the New Eng4hd Journal of Medicine notes to be ,``so strong as to be considered proof within the everyday meaning of the Vord." 14 It is lime for those concerned Hth health education and with the thics of advertising, at least in health and medical journals, to take note, further investigation should seek the fexact component of cigarette smoke-- r arsenic, or other--which is respon sible. The data also suggest that several eccupations (Table 9), in addition to , Jiose previously identified as having an etiological relationship, may be involved the development, of lung cancer, ihese occupations should now be insnsively studied to determine to what extent persons engaged in them suffer - special risk of lung cancer. There after, if an etiological relationship is clearly established, the precise exposure and mechanism responsible should be identified in order that protective meas ures may be introduced.
