Implementation of Lung Cancer Diagnosis based on DNN in Healthcare System

Cancer represents a kind of disease that is widespread throughout the world. Actually, there are several kinds of cancer. However, lung cancer represents the most prevalent cancer form and can lead to death with late healthcare. Therefore, it is essential to initialize therapy via diagnosing lung cancer for decreasing the death chance. Classification is one of the fundamental issues in the knowledge discovery fields and scientific decisions. There are many types of techniques used for constructing classifiers and cancer diagnosis. Recently, deep learning becomes a powerful and popular classification technique for many areas of medical data diagnosis in the healthcare systems. In this paper, an effective and accurate deep neural network (DNN) based lung cancer diagnosis implemented in the healthcare system has been proposed which includes three main phases; pre-processing, generating strong rules, and classification. The input data are pre-processed in the first phase. Because these data are entered from databases, so there are missing data that should be replaced with zero values. Then, data are normalized for speeding up the learning phase. After that, the class association rule is used to enhance the classification performance by generating frequent patterns inducible from the dataset which include features that are significant to the class attribute. Finally, DNN is utilized in the process of classification for obtaining a sample diagnosis estimate. DNN based diagnosis system was tested and evaluated on the lung cancer dataset which has 25 attributes and 1000 instances. The obtained results demonstrated that the proposed system achieved a high performance compared to other existing lung cancer diagnosis systems with 95% accuracy, 97% specificity, and 95% sensitivity.
