“Industrialized countries have disproportionately more cancers than countries with little or no industry (after adjusting for age and population size). One half of all the world's cancers occur in people living in industrialized countries, even though we are only one-fifth of the world's population. Closely tracking industrialization are breast cancer rates, which are highest in North America and northern Europe, intermediate in southern Europe and Latin America, and lowest in Asia and Africa.”
