AI cancer detection breakthrough
Early Detection
The AI system analyzes blood biomarkers, imaging data, and medical history to detect cancer up to five years before conventional diagnosis. Accuracy reaches 94% for 12 cancer types.
How It Works
Machine learning algorithms identify subtle patterns in routine blood tests that indicate early tumor development. The system flags patients for further testing before tumors become visible on scans.
Clinical Impact
Early-stage cancers are far more treatable. If deployed widely, the technology could prevent millions of cancer deaths annually. FDA approval is expected by mid-2026.
