Treatment of infertility and risk of breast cancer among women with a BRCA pathogenic variant: a matched case-control study

Findings from this large, international study found no evidence for an association between infertility or fertility treatment and the risk of breast cancer among BRCA1 or BRCA2 carriers. Although based on low rates of exposure, these findings provide some reassurance to BRCA carriers considering fertility treatment. Future studies evaluating impact of contemporary protocols are needed.

Abstract

Findings from this large, international study found no evidence for an association between infertility or fertility treatment and the risk of breast cancer among BRCA1 or BRCA2 carriers. Although based on low rates of exposure, these findings provide some reassurance to BRCA carriers considering fertility treatment. Future studies evaluating impact of contemporary protocols are needed.
