NEW YORK (Reuters Health) - Drinking does not appear to be associated with the overall incidence of prostate cancer, according to findings published in the International Journal of Cancer. However, men who drink alcohol may have a lower risk of having an aggressive prostate cancer and dying from this cancer.
"Although there is little evidence to support an association between alcohol consumption and prostate cancer risk, questions remain concerning the effect on aggressive and non-aggressive tumors and the pattern and type of alcohol consumed," Dr. Graham G. Giles and colleagues from the University of Melbourne, Australia, write.
To investigate, the researchers analyzed data on 16,872 men followed from 1994 to 2003. The participants ranged in age from 27 to 70 years at the beginning of the study, when questionnaires were used to obtain detailed information on alcohol consumption.
A total of 732 cases of prostate cancer occurred, including 132 aggressive cases and 53 prostate cancer-related deaths.
Overall, no association was observed between alcohol intake and the development of prostate cancer. Also, the pattern of drinking and type of alcohol were not significantly associated with prostate cancer risk.
Compared with abstainers, men who consumed 1 to 19 gram per day of alcohol, (no more than about one and a half drinks per day), had a slightly reduced risk of aggressive prostate cancers (34 percent). Prostate cancer mortality was also reduced in this group (44 percent).
According to the U. S. Department of Agriculture's Dietary Guidelines, 12 ounces of beer equals 12.9 grams of alcohol, 5 ounces of wine equals 13.5 grams, and 1.5 ounces of distilled spirits (80 proof) equals 14.0 grams of alcohol.
If it can be confirmed that moderate alcohol consumption protects against aggressive and fatal prostate cancer, it would have a "major impact," Giles and colleagues point out, because "there are no established modifiable risk factors for this common type of cancer."

纽约（路透社）－据发表在国际癌症杂志上的研究发现，饮酒没有显示出与前列腺癌总发生率相关。而且，饮酒男性发生进展性前列腺癌并死于这种疾病的风险更低一些。
来自澳大利亚墨尔本大学的Graham G. Giles及其同事写道：“虽然酒精摄入与前列腺癌风险之间的关系的证据还很少，但是现在问题主要在于进展性和非进展性癌症与酒精摄入的品种和方式。”
为进一步研究，研究者们分析了1994到2003年之间16872名男性的随访资料。入选者开始研究时年龄从27到70岁不等，均采用问卷调查获取酒精摄入的详细资料。总共有732例发生前列腺癌，包括53例前列腺癌相关性死亡。
总体上说，没有观察到酒精摄入和前列腺癌发生之间的关系，而且在酒精摄入方式和品种上也没有发现和前列腺癌有显著相关性。
与戒酒者比较，每日摄入19克酒精的男性（即每日不超过1.5杯），发生进展性前列腺癌的风险轻度降低（34％），该组前列腺癌死亡率也降低（44％）。根据美国农业部饮食标准：12盎司啤酒相当于12.9克酒精，5盎司葡萄酒相当于13.5克酒精，1.5蒸馏性酒相当于14克酒精。
如果能证实适度饮酒可以保护来自于进展性和致命性前列腺癌的风险，则可能发生较大影响。Giles及其同事指出：对这种常见的癌症目前还没有一种确定的可改变的风险因素。

看楼上的认领时间较长没有贴出来，我就先贴了，请原谅。 楼上的翻译的基本过关，对你的翻译稍做修改，有不同意见，一起商榷：
