Prediction of cancer incidence in Cracow and Bratislava

Projections for the incidence of all and selected major sites of cancer in the cities of Cracow and Bratislava were constructed for each year of the period 1978-1982 on the basis of data observed in the years 1968-1977. More or less increasing of unchanging trends were predicted for the malignant neoplasms of bladder, larynx and lung in males and of breast and ovaries together with decreasing trends of uterine cervix in females in the both cities. The trends predicted for the cancer of stomach in both sexes, of prostate and uterine corpus as well as of all sites in males showed different orientations in the compared cities. The factors connected with and usefulness of the adequate predictions of cancer incidence are discussed.
