Different BI-RADS breast cancer diagnosis using MobileNetV1 and vision transformer based on explainable artificial intelligence (XAI)
This comprehensive analysis distills key insights from cutting-edge research on AI-driven breast cancer diagnosis, highlighting its methodology, performance, and practical implications for enterprise applications.
Executive Impact: Revolutionizing Breast Cancer Diagnosis
Breast cancer (BC) remains one of the leading causes of death among women in the world. This work presents a hybrid deep learning (DL) framework for multi-class BI-RADS BC classification using mammographic images. The framework fuses MobileNetV1 for fine-grained local features with a Vision Transformer (ViT) for global contextual connections. Feature-level fusion is performed, followed by a bagging-based logistic regression (LR) classifier. The evaluation on the King Abdulaziz University BC Mammogram Dataset (KAUBC) demonstrates higher and stable performance across all BI-RADS categories, with accuracy (ACC), sensitivity (SEN), and specificity (SPE) exceeding 99%. Explainable AI (XAI) techniques like Grad-CAM and Grad-CAM++ provide clinically interpretable visual explanations, highlighting diagnostically relevant regions. This framework offers an effective, computationally structured, and explainable solution with strong potential for clinical decision-support.

Interpreting Model Decisions with Grad-CAM & Grad-CAM++
Explainable AI (XAI) techniques, Grad-CAM and Grad-CAM++, were applied to provide clinically interpretable visual explanations. These heatmaps highlight diagnostically relevant regions in mammograms, enabling radiologists to correlate the model's focus with their clinical knowledge, thereby improving trust and interpretability. For malignant cases, significant activation in areas with masses and clustered calcifications was observed. The analysis of misclassified cases, such as 'Probably Benign' classified as 'Suspicious Malignant' (Index 777), often occurred in visually ambiguous scenarios with dense fibroglandular tissue mimicking suspicious patterns, underscoring the challenges of subtle mammographic findings even for expert radiologists. This validates the model's focus on critical diagnostic cues and its alignment with clinical reasoning.
