Abstract: More and more young women are diagnosed with cancer. Radiotherapies and chemotherapies increase the survival rate of cancer patients, while their reproductive ability could be damaged by those anti-tumor treatments. At present, there are some reports about the fertility preservation in patients suffering from breast cancer and haematological malignances. According to the tumor types and other situations, the embryo cryopreservation, oocyte cryopreservation and ovarian tissue cryopreservation can be recommended as a personalized program of fertility preservation. Three kinds of freezing methods have their advantages and disadvantages. The embryo freezing and egg freezing need to extend the waiting time before anti-tumor treatment, but these technologies are relatively mature. Compared with them, the ovarian tissue cryopreservation do not delay the anti-tumor treatment, but the technology is not yet mature. The success rate of fertility preservation program is also affected by many factors, such as the age of patient, the type of tumor, and the specific treatment. In this paper, we reviewed in the research progress of fertility preservation of tumor women.
