Scientists have developed a small robot designed to detect and treat bowel cancer by navigating the digestive system and making 3D scans. Shaped like a mussel shell and guided by an external magnet, the robot aims to improve early detection and treatment of bowel cancer. Researchers from Leeds, Glasgow, and Edinburgh universities plan to begin human trials next year after successful pig testing. The robot, 3D-printed and the size of a UK penny, could streamline cancer screening and treatment processes, eliminating the need for traditional multi-stage biopsies. This innovation is seen as a potential breakthrough, significantly impacting the rapid and non-invasive diagnosis and treatment of cancer. Bowel cancer is the third most common cancer globally, with rising cases in younger populations possibly linked to diets high in ultra-processed foods. Further studies are required to confirm the robot’s safety, clinical effectiveness, and cost efficiency before it becomes a standard medical practice.
