Data indicate that most cancers appear to be related to environmental factors and that diet is one of these factors which appears to play a vital role. Epidemiologic evidence has increasingly implicated nutritional factors in the etiology of several forms of cancer in man. The effect of specific nutritional deficiencies, as well as unbalanced metabolism from dietary excesses, is discussed in relation to colon and breast cancer development. The possibility that excessive alcohol consumption among smokers, with its associated nutritional deficiencies, could act as a tumor promoter is discussed. It is timely to integrate the work of related specialties in cancer research, for cancer can no longer be viewed as a single disease with a single etiology.
数据表明，大多数癌症似乎与环境因素有关，而饮食是其中似乎起着至关重要作用的因素之一。流行病学证据越来越多地表明营养因素与人的几种癌症病因有关。针对结肠癌和乳腺癌的发展，讨论了特定营养缺乏以及饮食过量导致的代谢失衡的影响。还讨论了吸烟者过度饮酒及其相关营养缺乏可能作为肿瘤促进剂的可能性。整合癌症研究相关专业的工作正当时，因为癌症不能再被视为一种具有单一病因的单一疾病。
