Cancer in migrants to Uruguay.
Mortality rates from different cancers in the principal groups of migrants to Uruguay are compared with those in their countries of origin (Argentina, Brazil, Italy and Spain) and in the Uruguay-born population. Oesophageal cancer is very common in Uruguay and European-born populations, initially at low risk, appear to acquire rather higher rates after migration. For most migrants, the mortality from cancers of the breast, colon-rectum, corpus uteri and prostate is closer to the moderately elevated rates of Uruguay than those in their countries of origin. The results suggest that migrants to Uruguay undergo changes in some important environmental exposures, probably dietary, which give rise to substantial alterations in cancer risk within their lifespan.
