A similar effect is known for Japanese women who have very low breast
cancer rates (and high stomach cancer rates) in Japan, but not when they
immigrate to U.S. Many diseases have large geographical variations: in
New England, 22% of deaths are from cancer but in the Rocky Mountain
states, it is only 17%; and life expectancy is 2 years longer in West
north central states than in southeastern states. I don't think there
have been studies on whether these effects apply to people who have
moved, but it is generally assumed that they do. It seems to be believed
that different diets have a lot to do with it. There is abundant evidence
that cancer is principally an environmental disease, not heavily
influenced by genetics, but "environmental" includes diet and should not
be interpreted to mean pollution.
