Epidemiological evaluation of incidence of lung cancer in inhabitants of Warsaw in the period 1966--1975.

Lung cancer is most frequent in men and occupies the first place among the causes of cancer deaths. In the period 1956--1975 in Poland the incidence rate of lung cancer increased about ten times in men and seven times in women. Analysis of age-specific incidence shows a significant increase in the group age of 35--39 years in men and in 45--49 in women. The absolute increase of incidence of lung cancer, the poor prognosis and the high mortality should call the attention of the whole population to canecerogenic factors, especially the noxious influence of smoking.
