Lung cancer stands as the primary cause of cancer-related deaths globally, marked by a notable fatality rate owing to delayed diagnosis. Timely detection proves pivotal for efficacious treatment and enhanced patient prognosis. Within this study, we introduce an innovative methodology for identifying lung cancer, employing a fusion of 3D Convolutional Neural Networks (CNN), Support Vector Machines (SVM), and Radial Basis Function (RBF). This proposed method harnesses 3D CT scans to extract characteristics from lung nodules and categorize them as either malignant or benign. Initially, the 3D CNN is employed for feature extraction, capturing the spatial correlations and nodule patterns. Subsequently, the CNN's output is inputted into the SVM and RBF classifiers for further classification. Trained on the extracted features, the SVM and RBF classifiers undertake the final categorization of lung nodules. Experiments using a publicly available dataset of lung CT scans were carried out in order to evaluate the effectiveness of the suggested strategy. Our results demonstrate that the suggested strategy outperforms other modern approaches in achieving high accuracy in the identification of lung cancer. In particular, the suggested approach yields 96.2% accuracy, 96.6% sensitivity, 95.8% specificity, and 0.988 AUC. Combining 3DCNN, SVM, and RBF may increase lung cancer detection's accuracy and effectiveness, leading to earlier diagnosis and better patient outcomes. Additionally, there is a chance that this suggested approach will find use in other medical imaging fields, like the detection of prostate and breast cancer. To summarize, the proposed methodology signifies a noteworthy stride towards enhancing the precision and effectiveness of lung cancer detection, thereby promising a substantial impact on patient care and outcomes.
