虽然动物实验和描述性流行病学调查支持膳食因素(特别是脂肪摄入)与乳腺癌的危险有关,但是病例对照和群体流行病学分析的证据还不充分。本文将以往的十二篇对膳食与乳腺癌关系的病例对照研究报道结果进行了再分析。这十二项研究分别在不同膳食习惯和不同乳腺癌危险地区的人群中进行的,这些地区是阿根廷、澳大利亚、加拿大、中国、希腊、夏威夷、以色列和意大利。共有4427名病例和6095名对照。研究结果表明:绝经前妇女的乳腺癌危险因素与其体质指数(BMI)呈负相关。绝经后妇女的乳腺癌危

In this paper, the past 12 cases of diet and breast cancer case-control study reported results were re-analyzed.

Postmenopausal women with breast cancer risk
