Abstract: The incidence rate of ovarian cancer ranks the third among female malignant tumors, the mortality rate ranks the first and the prognosis is poor. Ovarian cancer poses a serious threat to the health of women's lives. The incidence of ovarian cancer is related to heredity, endocrine disorders and adverse lifestyle factors. In recent years, some scholars have carried out the impact of lifestyle, especially shift work, on the occurrence and development of ovarian cancer. Shift work can lead to circadian disruption, which affects hormonal balance in the body and may be a risk factor for ovarian cancer. This review summarizes four cohort studies and two case-control studies on the relation between shift work and ovarian cancer. The conclusion of the studies is inconsistent, suggesting that further researches are needed.
