[Cancer mortality in the Thurgau canton 1970 and 1980 with a comparison between urban and rural areas].

As an addition to the recently published data by the Swiss Statistics Office in cooperation with the Swiss Cancer Registry, this report presents a microanalysis of trends in Canton Thurgau (185 000 inhabitants) based on the corresponding data. In the course of only 10 years the number of deaths due to cancer in rural areas has come to equal to that in city areas. This trend is particularly obvious for bronchial carcinoma in men. The decrease in mortality due to carcinoma of the stomach is more obvious in the urban population than in rural areas, a trend in which it can be assumed that environmental factors play a role. Further developments must be observed carefully, and corresponding analyses should also be performed in other cantons.
