hence the horrible (and not always pointed out – optional) barium drinks:
“Japan has one of the highest rates of stomach cancer in the world, due to the Japanese diet: low in fat but high in salt and nitrates from traditionally preserved fish and vegetables.
Westerners have much lower rates of stomach cancer and so almost no medical back home would include a stomach screening by X-ray…
Meanwhile, the situation is reversed for colon cancers. These are much more common in the West due to the meat- and fat-rich diet favored there. When past a certain age, anyone eating a Western diet should have some form of colon cancer screening.
This is offered by the UK’s National Health Service to those who are over 60 years of age, while U.S. gastroenterologists recommend that patients aged over 50 have regular colonoscopies. Even an elaborate medical check in Japan may neglect this area.”
