Strategies and Obstacles in Curating Data for Breast Cancer Prediction Models: A Foundation for AI-Driven Models

Abstract

Breast cancer continues to impact millions globally, driving urgent demand for innovative tools to improve early detection. While AI and machine learning offer transformative potential in predicting breast cancer, their success hinges on overcoming significant data-related barriers. This work examines practical approaches to assembling robust datasets, such as tapping into open-access medical repositories, forging partnerships with hospitals and research networks, and combining diverse data streams—including clinical histories, imaging and molecular biomarkers. A key focus is ensuring datasets reflect varied demographics, geographies, and cancer subtypes to reduce algorithmic bias and enhance real-world applicability.

Despite these efforts, obstacles persist. Strict patient privacy laws, institutional hesitancy to share sensitive health data, and fragmented annotation practices often stall progress. Limited availability of comprehensively labeled datasets and disparities in imaging equipment or protocols further compound these issues. To address these constraints, this study advocates for adaptive methodologies, such as cross-institutional data alliances that anonymize and aggregate records ethically, semi-supervised learning to extract insights from partially labeled data, and expert-guided annotation frameworks to improve label consistency. Additionally, harmonizing imaging standards and promoting interoperable formats could streamline data integration. By prioritizing these collaborative and methodological innovations, researchers can cultivate richer, more inclusive datasets while adhering to ethical guidelines. Advancing these strategies not only refines AI model accuracy but also strengthens trust in their clinical deployment, offering a pathway to earlier interventions and equitable care for diverse patient populations.
