Live Birth in a 50-Year-Old Breast Cancer Survivor Using a Cryopreserved Embryo: A Case Report

This report describes the rare case of a woman who, after starting infertility treatment at age 44 and subsequently being diagnosed with breast cancer, successfully achieved a live birth at age 50. The patient underwent numerous assisted reproductive technology cycles, ultimately conceiving with a cryopreserved embryo that was created when she was 45 and stored for five years. To our knowledge, this is the first reported case of a live birth in a breast cancer survivor at the age of 50, achieved through the use of her own cryopreserved embryo. This case represents a remarkable success achieved despite the combined challenges of advanced maternal age and a cancer diagnosis, highlighting the importance of persistent embryo banking and oncofertility.
