Abstract:
Objective To evaluate the relationship between the risk of breast cancer and abortions among nulliparous women. Methods Searched the data of Cochrane Library and PubMed before June 2014 to identify potentially studies which involved the relationship between the risk of breast cancer and abortions among nulliparous women. Data was extracted by two independent authors from each study. STATA software was used for statistical analysis. Calculated the pooled RR and 95% CI as the assessment of the link between abortions and breast cancer in fixed effects models. Results 13 studies were included. The study showed the RR and 95%CI of the relationship between the risk of breast cancer and abortions was 0. 98[0. 89,1. 08],P>0. 05 in nulliparous women, and the number of abortions was not associated with the risk of breast cancer. The RR and 95%CI of the relationship between the risk of breast cancer and induced abortions or spontaneous abor-tions were 0. 96[0. 88,1. 04],1. 01[0. 88,1. 14], respectively. Conclusion There is no correlation between breast cancer and abortions a-mong the nulliparous women, and the risk of breast cancer would not increas as the number of abortions increase.
