Abstract

Background: Breast cancer remains the most frequently diagnosed malignancy in women worldwide, and its clinical heterogeneity imposes formidable challenges on treatment standardization and outcome prediction. The emergence of artificial intelligence (AI) and multimodal data integration strategies is fundamentally reshaping how genomic, histopathological, radiological, and electronic health record (EHR) data are synthesized into actionable clinical intelligence.


Methods: We conducted a narrative review of peer-reviewed literature published between 2015 and 2026, focusing on AI-driven approaches to genomic profiling, digital pathology, radiomics, natural language processing (NLP) of clinical text, and multimodal data fusion in the context of breast cancer diagnosis, prognosis, and treatment planning.


Results: AI-based frameworks have demonstrated superior performance compared with conventional single-modality approaches in subtype classification, treatment response prediction, and biomarker discovery. Deep learning architectures applied to whole-slide imaging, convolutional neural networks in radiomics, graph-based genomic models, and transformer-based NLP pipelines each contribute distinct and complementary dimensions to precision breast oncology. Multimodal fusion models integrating two or more data streams consistently outperform unimodal counterparts in prognostic accuracy.


Conclusions: Multimodal AI represents a convergent approach capable of operationalizing the biological complexity of breast cancer at the point of clinical care. Realizing this potential requires rigorous prospective validation, harmonized data standards, explainability frameworks, and equitable implementation strategies. Future models must be adaptive, continuously learning, and grounded in real-world clinical evidence.
