AI-Driven Breast Cancer Diagnosis
Revolutionizing Early Detection and Patient Outcomes
Breast cancer remains a leading cause of cancer-related mortality among women worldwide. Early and accurate diagnosis significantly improves patient outcomes. This systematic review examines how artificial intelligence (AI) and deep-learning technologies are transforming breast cancer diagnosis across multiple imaging modalities, including mammography, ultrasound, MRI, molecular breast imaging, PET, and histopathology. Our findings indicate that AI models can achieve diagnostic accuracies exceeding 96% in certain contexts, supporting radiologists in detecting subtle abnormalities and reducing false positives. However, challenges remain regarding dataset standardization, model generalizability, and clinical integration. We emphasize the importance of explainable AI techniques to foster clinician trust and highlight future directions for translating these innovations into routine clinical practice.

Building Trust and Transparency with Explainable AI
Explainable AI techniques are vital for fostering clinician trust and enabling better decision-making by clarifying how complex AI models arrive at their breast cancer diagnoses.
Key Explainable AI Techniques
Explainable AI (XAI) is crucial for building trust and ensuring accountability in clinical decision-making. These techniques provide transparency into how AI models arrive at their predictions.
- LIME (Local Interpretable Model-agnostic Explanations)
- Perturbs input data to construct local surrogate models, mimicking black-box predictions to explain individual instances. Helps understand tissue density and lesion descriptions.
- SHAP (SHapley Additive exPlanations)
- Quantifies the contribution of each feature to the model prediction, offering both local and global interpretability. Reveals factors like tumor size, shape, and density.
- Grad-CAM (Gradient-weighted Class Activation Mapping)
- A visual technique highlighting crucial image regions for the model's prediction. Particularly useful for interpreting image-based models in BC diagnosis.
