Meta-analysis of study on risk factors of female breast cancer / 中华疾病控制杂志

ABSTRACT

50 years (ORs=1.39,95% CI1.22～1.57) and oral contraceptive use (Adjusted ORs=2.12,95% CI1.24～3.62) were associated with increase in breast cancer risk while the summary OR based on number of full-term pregnancy ≥1 (Adjusted ORs=0.63,95% CI0.60～0.68) and breastfed (ORs=0.76,95% CI0.64～0.90) indicated no association with breast cancer risk. Conclusions Decreasing benign breast disease, advocating breastfed and examining high risk population will be the effective measures to control breast cancer in women.
