PRL and breast cancer: Sertraline use was associated with a modestly increased breast cancer riskAge‐adjusted odds ratio (AOR): 1.58 (95% CI: 1.03–2.41)Multivariate‐adjusted odds ratio: 1.45 (95% CI: 0.88–2.40); not statistically significantNo clear association with duration, timing, or recency of useThe elevated risk for SSRIs overall was also statistically significant in age‐adjusted models (AOR: 1.33; 95% CI: 1.07–1.66), but not in fully adjusted analysesPotential mechanisms include elevated prolactin and altered estrogen or carcinogen metabolism via cytochrome P450 pathways
