ABSTRACT
The link between diet and cancer is firmly established in principle. A lively article highlighted some reviews of issues related to cancer and diet. Cancer epidemiologists are eager to exploit Europe’s opportunities to understand the causes of cancer. The expression “colorectal cancer” refers non-specifically to three cancers with distinctive epidemiologic and etiologic features. A large case–control study of dietary fiber and colorectal cancer conducted at SUNY–Buffalo added to the evidence for sex and site differences in response to fiber components. A carefully reasoned review of admittedly meager data concluded that intestinal exposure to ingested iron may be an important determinant of colorectal cancer risk in humans. A hospital-based case–control study of stomach cancer in high- and low-risk areas of the Federal Republic of Germany identified several possible diet-related risk factors. Adams briefly reviewed the literature on relationships between hormones, fat, and breast cancer.
