Abstract:  Cervical cancer, endometrial cancer and ovarian cancer are three common malignant tumors in gynecology. At present, the age of onset tends to be younger. Although gynecological malignancies are not common in pregnancy, epidemiological studies have been confirmed that the incidence rate of these diseases has been increasing in recent years. Cervical and ovarian cancers are the most common gynecological cancers in pregnancy, and endometrial cancer is rare in pregnancy. Due to the complexity of clinical management of gynecological malignancies during pregnancy, its treatment methods have been paid more attention. It is necessary to comprehensively consider the tumor stage, differentiation degree, histological type, gestational week, wishes of patients and possible fetal outcomes, comprehensively evaluate the condition of the disease and formulate individualized treatment plan.
