Abstract
Globally, breast cancer is the most common form of cancer and affects millions of women each year. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is considered an effective modality for diagnosing breast cancer. However, despite its widespread use in breast cancer classification, the diagnostic performance of DCE-MRI remains suboptimal, with frequent occurrences of misclassification. This article introduces a deep learning (DL) approach, termed the dual attention deep convolutional neural network (DADCNN), for classifying breast cancer as benign or malignant. The proposed method is evaluated using the DCE-MRI, RIDER Breast MRI, and Breast MRI datasets. Preprocessing is conducted through data augmentation techniques to increase dataset variability. The augmented data is then passed through a feature extraction process utilizing DenseNet-121 and ResNet-101 architectures. The extracted features are fused using a feature fusion model, followed by classification to determine the cancer type. The DADCNN model effectively manages long input features by selectively focusing on the most relevant aspects of the breast lesion, thereby enhancing classification accuracy. Experimental results demonstrate that the proposed approach outperforms existing methods, including the multi-modality network (MUM-Net) and the multivariate rocket algorithm, across all evaluated performance metrics. The DADCNN approach improves classification accuracy of 0.954, 0.992 and 0.990 on the DCE-MRI, Breast MRI and Rider Breast MRI datasets respectively by leveraging dual attention mechanisms to focus on the most relevant features associated with breast cancer.
