Breast cancer is a leading cause of death amongst women, several studies have shown significant association between alcohol consumption and breast cancer. The aim of this overview is to highlight some of the mechanisms by which alcohol consumption could increase the risk of developing breast cancer. Using online Medline search engine, article containing details about mechanisms which explain the link between alcohol and breast cancer were examined. A number of mechanisms were found by which alcohol could increase the risk of breast cancer, alcohol's interaction and effect on oestrogen secretion; number of oestrogen receptors; the generation of acetaldehyde and hydroxyl free radicals; cells migration and metastasis; secretion of IGF1 and interaction with HRT and folate metabolism. In conclusion, it is essential for clinicians to understand these mechanisms and inform patients of the link between alcohol and breast cancer.

乳腺癌是女性死亡的主要原因之一,多项研究表明饮酒与乳腺癌之间存在显著关联。本综述的目的是强调饮酒可能增加患乳腺癌风险的一些机制。使用在线医学文献数据库检索引擎,对包含解释酒精与乳腺癌之间联系机制细节的文章进行了审查。发现了多种酒精可能增加乳腺癌风险的机制,包括酒精与雌激素分泌的相互作用和影响;雌激素受体的数量;乙醛和羟基自由基的产生;细胞迁移和转移;胰岛素样生长因子1的分泌以及与激素替代疗法和叶酸代谢的相互作用。总之,临床医生必须了解这些机制,并告知患者酒精与乳腺癌之间的联系。
