Background:Breast cancer and endometriosis are two significant diseases that threaten the health of female worldwide.The relationship between them is still in a state of controversy.In present study,we identified the risk of breast cancer in patients with endometriosis through a meta-analysis.Methods:A systematic search of the PubMed,Embase and Cochrane Library,with the terms for endometriosis,breast and cancer,tumor,neoplasm,or carcinoma combined.Studies on related risk estimates of endometriosis and breast cancer were included in the meta-analysis.Furthermore,a series of analytical methods such as sensitivity analysis,the Cochran Q test,Begg’s and Egger’s test were used to analyze the information of collected studies.Results:Finally,a total of 8 studies were included.After statistical analysis based on STATA software,the combined odds ratio of the results was 1.13(95%CI:1.09–1.17).And the results of subgroup analysis showed that the odds ratio values of different outcome indexes were 1.06(95%CI:1.02–1.09,P<0.05),the effective effect estimates were presented in SIR(P=0.006,I^(2)=80.3%).Conclusion:In present study,we identified that patients with endometriosis have an increased risk of breast cancer.It is worth considering that our research was a summary analysis of epidemiological data.More in-depth studies are needed to determine the pathophysiology of this relationship.
