《英国酒精和酒精中毒杂志》第14卷第3期(1979年)报道:关于酒精及其致癌作用的评论文章表明,某些与酒精中毒密切相关的人癌是存在的。纽约医学院外科付教授洛温费尔斯(Albert Lowenfels)医生指出,由于多数重度饮酒者也吸烟,所以要估价因酒精而引起的癌症危险性的增加极其困难。不过各种不同的研究表明,重度饮酒者发生癌症危险性的增加为30％。至今还没有酒精直接致癌的实验证明,不过已知强烈致癌物亚硝胺是机体从食物中合成的,其中包括酒精。酒精促使形成癌瘤的其它机理包括:酒精引起维生素缺损及酶诱导作用。维生素缺损常
The British Journal of Alcohol and Alcoholism, Vol. 14, No. 3 (1979) reports that articles on alcohol and its carcinogenicity suggest that certain human cancers that are closely related to alcoholism exist. Dr. Albert Lowenfels, professor of surgical surgery at the New York School of Medicine, pointed out that because most heavy drinkers also smoke, it is extremely difficult to assess the risk of cancer caused by alcohol. However, various studies have shown that the risk of cancer increases for heavy drinkers is 30%. There has been no evidence of direct carcinogenicity of alcohol, but nitrosamines, which are known to be potent carcinogens, are synthesized by the body from food, including alcohol. Other mechanisms by which alcohol contributes to the formation of cancer include alcohol-induced vitamin deficiency and enzyme induction. Vitamin deficiency often
