Machine Learning based Intelligent System for Breast Cancer Prediction (MLISBCP)

Risks of death from Breast Cancer (BC) are drastically rising in recent years. The diagnosis of breast cancer is time-consuming due to the limited availability of diagnostic systems such as dynamic MRI, X-rays etc. Early detection and diagnosis of breast cancer significantly impacts life expectancy as current medical technologies are not advanced enough to treat patients in later stages effectively. Even though researchers have created many expert systems for early detection of BC such as WNBC, AR + NN system, AdaBoost ELM etc., but still most expert systems frequently lack adequate handling of the class imbalance problem, proper data pre-processing, and systematic feature selection. To overcome these limitations, this work proposes an expert system named "Machine Learning Based Intelligent System for Breast Cancer Prediction (MLISBCP)" for better prediction of breast cancer using machine learning analytics. The suggested system utilises the 'K-Means SMOTE' oversampling method to handle the class imbalance problem and 'Boruta' feature selection technique to select the most relevant features of the BC dataset. To understand the effectiveness of the proposed model - MLISBCP, its performance is compared with various single classifier based models, ensemble models and various models present in literature in terms of performance metrics- accuracy, precision, recall, F1-score and RoC AUC Score. The results reveal that the MLISBCP obtained the highest accuracy of 97.53 % with respect to existing models present in the literature.
