[Geography of lung cancer incidence among women and men of Upper Silesia in the years 1986-1990]. / Geografia zachorowalnosci na raka pluca wsród mezczyzn i kobiet na Górnym Slasku w latach 1986-1990.

During a five period (1986-1990) in Katowice province (Upper Silesia) there were 6,140 cases of lung cancer in males and 1,039 females recorded. The standardized (according to age structure of the world population) incidence of lung cancer in both groups, in 93 administrative units (45 cities, 48 communities) significantly vary and are geographically unevenly distributed. The incidence in selected areas in males can be compared with values characterizing regions of the world with highest indices (> 95 per 100,000); whereas in females the incidence of lung cancer is much lower. The prognosis for lung cancer incidence in the Upper Silesia, according to the regression analysis is pessimistic.
