The effect of the polycystic ovary syndrome and hypothyroidism on the risk of fibrocystic breast changes: a meta-analysis

Abstract: This meta-analysis aimed to determine the pooled association between polycystic ovary syndrome (PCOS), hypothyroidism, and fibrocystic breast changes. We searched important databases, including PubMed (Medline), Scopus, Web of Science, and Embase to retrieve all relevant studies published from 1990 to April 2021. The bias risk of selected articles was assessed based on the JBI checklist. Our search strategy yielded a total of 487 articles from the international databases. After screening their full-texts, 6 ar… Show more

“…For the normal menopausal group, the most common pathologies were also cyst (53.7%) and cystic changes (17.9%). Our results also showed a significantly higher rate of fibroadenoma in women with early menopause (p value=0.032), which is consistent with previous results (12)(13)(14).…”

“…It is also important to note that the overall rate of malignant breast masses in post-menopausal women is much higher than in women of childbearing age, which is evidence that hormonal cycles during fertility have a protective effect against malignancies (17,18). The rate of breast cysts in women who have menstrual cycles is significantly higher than in menopausal women due to the high impact of cysts on hormonal cycles (14,15). This phenomenon is significantly reduced in post-menopausal women but remains in early-menopausal women (16,17).…”

“…However, the exact cause of these changes remains unclear. Certain conditions that cause hormonal imbalances, such as polycystic ovarian syndrome (PCOS), have also been associated with an increased risk of FCCs [ 3 , 4 ]. Evaluation of FCCs is typically performed by mammography, ultrasonography, and biopsy.…”
