[Fertility preservation strategies in young women in case of breast cancer or hematologic malignancy].

The incidence of cancer in young patients as well as survival rates is steadily increasing. The question of fertility capacity is therefore of great importance regarding the quality of life after cancer. According to the ASCO recommendations, every patient should be advised about the chemotherapy-induced ovarian damage and fertility preservation possibilities. Several options can be discussed: embryo and/or oocytes freezing and ovarian tissue cryopreservation. Fertility preservation techniques are progressing rapidly but it still remains difficult to establish precise flow-charts according to age, marital status, type, dose and timing of chemotherapy.
