Preliminary study on the risk assessment model of breast cancer in Bengbu

Objective:To screen the risk factors of breast cancer in Bengbu women,establish the risk assessment model of breast cancer,investigate the cut-off points of low,medium and high risk,and assess the probability of breast cancer in women with specific risk factor.Methods:The risk factors of breast cancer were screened by logistic regression,and which was used to establish the risk assessment model of breast cancer.The risk model was evaluated using Fisher.The model performance was examined by the area under the ROC curve,and the appropriate low,medium and high risk cut-off points were distinguished by the ROC curve.Results:The family economy condition,eating bean product,releasing negative emotion,work intensity and screening breast cancer were the main risk factors of breast cancer(P <0.05 to P <0.01).The risk model showed that the women with P ≤ 0.49,0.49 <P <0.51 and P ≥ 0.51 were low,medium and high risk populations,respectively.Conclusions:The model can assess the probability of breast cancer in Bengbu women with specific risk factor,and provide certain basis in establishing the screening criteria.
