Micro-Robots offer real-time cancer detection without biopsy

In a breakthrough that could revolutionize cancer diagnosis, UK scientists have developed micro-robots capable of performing real-time, non-invasive 3D scans to detect and diagnose colorectal cancer. Developed through a collaboration between the Universities of Leeds, Glasgow, and Edinburgh, the oloid magnetic endoscope (OME) is just 21mm wide and can navigate the gastrointestinal tract to generate high-resolution ultrasound images.

Published in Science Robotics, the study marks the first successful use of a magnetically controlled robot to scan inside the gut. The technology could replace traditional biopsies, drastically cutting the weeks-long wait for lab results and enabling immediate diagnosis.

Researchers say this could streamline colorectal cancer detection and treatment into a single procedure, reducing patient discomfort and delays. Future developments may also include targeted drug delivery. As colorectal cancer remains a leading cause of death globally, this innovation offers a promising leap toward faster, safer care.
