Abstract

Background: Often young women affected with BRCA1/2 positive breast cancer have not finished or even not started their childbearing before the onset of the disease. The aim of our mini-review is to summarize state of art knowledge on pregnancy after breast cancer in BRCA1/2 carriers.

Methods: A broad review of the literature was conducted using MEDLINE (via PubMed) for relevant articles published. This review summarizes the impact of different cytotoxic agents on a fertility, fertility preservation, maternal and fetal prognosis after pregnancy in breast cancer survivors with BRCA1/2.

Conclusion: According to the existing literature evidence pregnancy after therapy for breast cancer in BRCA carriers is safe for the mother and offspring, but patients' needs, oncofertility counseling and fertility-sparing strategy should be carefully planned before starting the cytotoxic treatment.

Keywords: BRCA1/2 carriers; Breast cancer; Fertility preservation.
