The risk factors for epithelial ovarian cancer were studied with a 1: 2 ratio case-control study. The results of conditional logistic regression analysis showed that the occurrence of ovarian epithelial carcinoma was the result of multi-factor comprehensive effect. The first-degree relatives had the history of malignant tumor, infertility and abnormal menstruation had obvious connection with ovarian cancer and inhibited the ovulation. Mumps virus infection has nothing to do with the occurrence of ovarian cancer.
