Hereditary breast and ovarian cancer syndrome （HBOC） is one of hereditary tumor patients whose fertility is a problem. This disease is characterized by the onset of early-onset breast cancer， and it causes great conflict for patients in trying to balance both cancer treatment and pregnancy， both of which are time-constrained. Embryo cryopreservation， oocyte cryopreservation， and ovarian tissue cryopreservation are considered as possible fertility preservation treatment for HBOC patients with cancer.
