Polycystic ovary syndrome (PCOS) is the most common hormonal disorder in women of reproductive age. There is no clear association between PCOS and benign breast disease (BBD). The latter is a frequent benign disorder, affecting women between 20 and 50 years of age. To date, the classification remains controversial, and the risk of developing breast cancer that is associated with these changes is different depending on the histopathological findings. The most frequent changes are breast cysts, which are noted in up to 50% of patients older than 30 years of age. This up-to-date review presents the relationship between PCOS and BBD. In conclusion, there is no clear association between benign breast disease and PCOS. Further studies on a large population with prospectively collected data using updated PCOS criteria are necessary.

多囊卵巢综合征和纤维囊性乳腺疾病：最新综述

多囊卵巢综合征 (PCOS) 是育龄妇女最常见的激素紊乱。PCOS 与良性乳腺疾病 (BBD) 之间没有明确的关联。后者是一种常见的良性疾病，影响 20 至 50 岁的女性。迄今为止，该分类仍有争议，与这些变化相关的乳腺癌风险因组织病理学发现而异。最常见的变化是乳房囊肿，在 30 岁以上的患者中，多达 50% 的患者会出现这种情况。这篇最新评论介绍了 PCOS 和 BBD 之间的关系。总之，良性乳腺疾病和 PCOS 之间没有明确的关联。有必要使用更新的 PCOS 标准对大量人群进行前瞻性收集的数据的进一步研究。
