Cancer mortality in 1962-66 among Polish migrants to Australia.

The 1962-66 cancer mortality of Polish migrants to Australia is compared with the cancer mortality prevailing in Poland and in Australia. Small numbers compel to limit the analysis to the most frequent cancer sites only.The main findings are:(a) Stomach cancer mortality of Polish migrants to Australia is intermediate between the high mortality in Poland and the much lower one in Australia.(b) Intestinal tract and breast cancer mortality of Polish migrants is displaced upwards, from the low Polish level to the much higher Australian one.(c) Lung cancer mortality of Polish male migrants does not differ distinctly from the mortality observed both in the country of origin and of adoption of these migrants.The presented findings are compared with the results of a similar study of Polish migrants to the U.S. Aims for future studies are briefly outlined.
