0Fragmentia-AI is a pioneering artificial intelligence framework designed to detect cancer by analyzing the "biological language" of cell-free DNA (cfDNA) fragments. Unlike traditional liquid biopsies that search for rare genetic mutations, this language model identifies subtle structural patterns and sequence motifs inherent in tumor-derived DNA. This methodology allows for highly accurate cancer screening and minimal residual disease (MRD) monitoring using ultra-low sequencing depth, significantly reducing clinical costs. Research confirms that the model generalizes effectively across 17 different cancer types and remains robust even when traditional tumor mutations are undetectable. Furthermore, the system provides valuable prognostic insights for patients following surgery or immunotherapy by identifying persistent cancer signals. Ultimately, Fragmentia-AI represents a shift toward scalable and accessible oncology by leveraging deep learning to decode the complex topological signatures of malignancy.
