Abstract
OBJECTIVE: To detect the risk factors of breast cancer in women living in Chengdu in order to identify high risk population and to conduct proper interventions. METHODS: A matched case-control study was performed in 265 cases with breast cancer who lived in this area. RESULTS: In the univariate analysis, menarche to menopause period > or = 35 years, taking oral contraceptives, history of benign breast diseases, passive smoking, and syrup drinking are the statistically significant risk factors of breast cancer, whereas breast feeding and soybean food consumption are protective factors. Conditional logistic multivariate analysis revealed that history of benign breast diseases and passive smoking are risk factors while soybean food products and breast feeding are protective factors. CONCLUSION: The risk factors of breast cancer in women living in Chengdu are history of benign breast diseases and passive smoking.
