Canadian cancer statistics
While the above are figures for Canada, there is a marked difference between the major cancersaffecting the developing world and the developed world. Thus, cancer of the liver is the most frequentin China, and other Asian countries as well as west and central Africa. Cancer of the liver isattributable in these countries to the high incidence of hepatitis B infection and contamination of foodsby aflatoxin. On the other hand, colon-rectal cancer is more prevalent in North America, Europe andAustralia, apparently associated with a western diet – high in saturated fat and low in fibre, fresh fruitand vegetables.
