A 43-year-old woman with an associated history of gynecological pathology and breast cancer with only one cryopreserved embryo wished to be a mother. Several factors that influenced the success of the pregnancy in this case were analyzed. Favorable factors included: triple positive breast cancer [positive hormone receptors and positive human epidermal growth factor receptor 2], which is more hormosensitive and chemosensitive; absence of metastasis; correct endometrium preparation; and the patient’s optimistic attitude and strict health habits. In contrast, the factors against success were: breast cancer; adjuvant breast cancer therapy gonadotoxicity; the age of the patient (> 40-year-old); endometriosis; ovarian cyst; hydrosalpinx; submucosal fibroids and the respective associated surgery done for the above-mentioned pathology (all resolved prior to the embryo transfer); and a low quantity of ovules (low ovarian reserve) after ovarian stimulation. This is a very special clinical case of a patient with theoretically low pregnancy success probability due to the consecutive accumulation of gynecological and oncological pathologies, who nonetheless became pregnant and delivered a full-term infant and was able to provide adequate breastfeeding.
