Larynx cancer risk factors.
The larynx cancer relative risk has been evaluated (328 cases) in the stationary-native Upper Silesians (63.7%) and migrating (36.3%) male population. The particular control groups (656 men) included 418 and 238 men respectively not suffering from malignant neoplasms. The essentially higher larynx cancer incidence risk has been shown for men manual labor and exposed to the influence of various dusts, gases and vapors and other pollutants in their place of work. The increased substantial incidence risk is also true for men who smoke tobacco and are professionally exposed to the pollution. The results in regard to the consumption of raw and boiled vegetables suggest that these may be inhibitors of the neoplasmatic process in the area of larynx (although not only). The frequency of the consumption of alcohol--vodka or beer--increases the larynx cancer incidence risk both among autochthons and immigrants. Nevertheless, the data concerning the amount of alcohol consumed are less valuable here; they do not allow to establish fully reliable quantitative levels of the beer or vodka consumed. In comparison with the literature of the subject, divergent data have been obtained as far as the joint influence of drinking alcohol with simultaneous smoking of tobacco and professional exposure are concerned.
