Local inflammation after tubal ligation may affect ovarian function and breast cancer risk.
We analysed tubal ligation, menopausal characteristics, and breast cancer risk in the Sister Study cohort (N=50,884 women).
Tubal ligation was associated with hot flashes (hazard ratio (HR) 1.09; 95% confidence interval (CI): 1.06-1.12) but not menopausal age (HR 0.99; 95% CI: 0.96-1.02). Tubal ligation did not have an impact on breast cancer overall (HR 0.95; 95% CI: 0.85-1.06), but had a suggested inverse relation with oestrogen receptor+/progesterone receptor+ invasive tumours (HR 0.84; 95% CI: 0.70-1.01), possibly because of subsequent hysterectomy/bilateral oophorectomy.
Tubal ligation does not influence overall breast cancer risk.
输卵管结扎后的局部炎症可能会影响卵巢功能和乳腺癌风险。
我们分析了姐妹研究队列（50884 名女性）中的输卵管结扎、绝经特征和乳腺癌风险。
输卵管结扎与热潮红相关（风险比 (HR) 1.09；95%置信区间 (CI)：1.06-1.12），但与绝经年龄无关（HR 0.99；95% CI：0.96-1.02）。输卵管结扎对总体乳腺癌没有影响（HR 0.95；95% CI：0.85-1.06），但与雌激素受体+/孕激素受体+浸润性肿瘤呈负相关（HR 0.84；95% CI：0.70-1.01），可能是因为随后的子宫切除术/双侧卵巢切除术。
输卵管结扎不会影响总体乳腺癌风险。
