5-alpha Reductase inhibitors and risk of male breast cancer: a systematic review and meta-analysis

Conclusion: We did not observe a positive association between the use of 5ARIs and MBC. The small number of breast cancer cases exposed to 5ARIs and the lack of an association in our study suggest that the development of breast cancer should not influence the prescribing of 5ARIs therapy.
