## Summary

The tool covers **75 percent of U.S. breast cancer cases**, according to the company, and uses **proprietary spatial AI modeling** on existing MRI data without additional procedures or hardware.

The clearance follows a **blinded, multi-institutional retrospective study** of **2,129 patients** from Mayo Clinic, Emory University, Stanford Medicine, and Mercy Medical Cedar Rapids. The algorithm was trained on **1,133 samples** from six U.S. The tool integrates with **GE and Siemens MRI scanners** and is positioned as a complement to genomic assays, offering earlier risk insights.

## Key points

- FDA cleared TumorSight Risk for hormone receptor-positive, HER2-negative breast cancer patients in Stage I–IIIA
- Study of 2,129 patients showed high-risk patients had 3.3x greater recurrence risk than low-risk patients

## Why it matters

This is the first FDA-cleared AI tool for breast cancer recurrence risk using MRI data, potentially shifting earlier care planning beyond genomic assays.
