ABSTRACT
Britain tops the international table, alas, with a death rate five times that of Japan. Now that there is a lot of information on migrant populations, we know that Japanese who emigrate to America soon share American death rates for most common cancers. While this has not yet come true for breast cancer, there is evidence to suggest that it will. Thus the information from migration suggests that environmental factors play a large part in the onset of the disease. Despite intensive study, it is disappointing to report that no clear guidance as to how to reduce risk through diet has emerged.
