BRCA1 and breast carcinoma: In 2009, Sagi et al. [76] described 10 patients with a BRCA1 or BRCA2 mutation, aged 29 to 38 years old, who had a PGT consult: three of them had a previous breast cancer, but none were in the process of reusing cryopreserved material, and eight of them were already considering IVF for previous infertility.
