Intelligent detection of breast cancer with feature selection based on logistic regression and support vector machine Classification

Breast cancer is the most common cancer among women and the existence of a precise and reliable system for the diagnosis of benign or malignant of this cancer is essential. Nowadays, using the results of needle aspiration cytology, data mining and machine learning techniques, early diagnosis of breast cancer can be done with greater accuracy. In this study, we propose a method consisting of two steps: in the first step, to eliminate the less important features, logistic regression has been used to select more important features. In the second step, the Support Vector Machine (SVM) classification algorithm has been used with three different kernel functions for the diagnosis of benign and malignant samples. To evaluate the performance of the proposed method, two data sets, WBCD and WDBC have been used with investigation of several metrics such as precision, the Area Under the ROC (AUC), true positive rate, false positive rate, accuracy and the F-measure. The results show that using the logistic regression method, it is possible to select the more efficient features, such that the proposed method reaches 98.69% in terms of classification accuracy.
