Breast Cancer Risk Assessment for Screening: A Hybrid Artificial Intelligence Approach
This study evaluates whether integrating clinical data with mammographic features using artificial intelligence (AI) improves 2-year breast cancer risk prediction compared to using either data type alone. A hybrid model combining diverse data sources demonstrated superior predictive performance and robustness across varying breast densities, enabling more personalized screening strategies and supporting early detection.
Executive Impact: Revolutionizing Breast Cancer Screening
Our analysis of this pioneering research reveals how a hybrid AI approach to breast cancer risk assessment can significantly enhance early detection and personalize screening protocols. By integrating clinical and mammographic data, organizations can achieve a more accurate and robust prediction model, leading to optimized resource allocation and improved patient outcomes. This translates into tangible benefits, including increased diagnostic accuracy, reduced radiologist workload, and the potential for earlier intervention in high-risk individuals.

Hybrid Model AUC (95% CI: 0.71–0.76)
| Model | Mean AUC | CI (95%) |
|---|---|---|
| ERTpd (Personal Data Only) | 0.59 | [0.55, 0.61] |
| ERTim (Image Features Only) | 0.73 | [0.69, 0.75] |
| ERTpd + im | 0.74 | [0.70, 0.76] |
| CNN (Mammograms Only) | 0.74 | [0.70, 0.75] |
| ERTpd+im + CNN (Hybrid) | 0.75 | [0.71, 0.76] |
The hybrid model integrating clinical and mammographic data significantly outperformed the CNN model (p < 0.05) and slightly surpassed the ERTpd + im model. Individual models (ERTpd, ERTim) showed lower predictive power, highlighting the synergistic benefits of combining data types.
Advanced Insights: Robustness and Feature Influence
Robustness Across Density: The hybrid model demonstrated consistent performance across all breast density quartiles (p > 0.05), indicating its reliability regardless of breast composition. This is crucial for real-world application, as breast density is a known challenge in mammography screening.
Screen-Detected vs. Interval Cancers: The model performed significantly better for screen-detected cancers (AUC 0.79) than for interval cancers (AUC 0.59, p < 0.001). This highlights the model's strength in identifying visible malignancies at screening, while also pointing to areas for future improvement in predicting occult or rapidly progressing cancers.
Feature Importance: Analysis showed that CNN model variables were the most influential (average MDI 0.012), followed by conventional image-extracted features (im) (average MDI 0.004). Personal data (pd) had the lowest impact (average MDI < 0.002), though previous benign breast disease, education level, and family history were notable within this group.
AI Explainability (Grad-CAM): Visualizations demonstrated the CNN model's ability to focus on specific mammographic regions, often related to dense tissue or parenchymal patterns, for its predictions, even in the absence of visible lesions. This enhances trust and understanding of the AI's decision-making process, moving beyond black-box predictions.
