Feature Selection from Image Descriptors Data for Breast Cancer Diagnosis Based on CAD

Breast cancer is an important public health problem worldwide among women. Its early detection generally increase the survival rate of patients, however, is one of the biggest deficiencies to the present. The purpose of this paper is to obtain a model capable of classifying benign and malign breast tumors, using a public dataset composed by features extracted from mammography images, obtained from the Breast Cancer Digital Repository initiative. Multivariate and univariate models were constructed using the machine learning algorithm based on CAD, Random Forest, applied to the images features. Both of the models were statistical compared looking for the better model according to their fitness. Results suggest the multivariate model has a better prediction capability than the univariate model, with an AUC between 0.991 and 0.910, however, they were found five specific descriptive features that can classify tumors with a similar fitness as the multivariate model, with AUCs between 0.897 and 0.958.
