Lighting the way to cancer surgery

Lighting the way to cancer surgery By decoding the subtle timing of light, scientists could give surgeons sharper vision in the operating room – and patients a brighter outlook beyond it. Light has always been a guide for discovery. We have been using it to explore the Universe with telescopes, to reveal microscopic worlds with microscopes, and increasingly, to peer into the mysteries of our own bodies. In medicine, light is more than just a way to see: it can expose what is hidden, revealing details invisible to the naked eye. Furthermore, light is non-invasive, meaning that crucial information can be retrieved without damaging the target. Among the most fascinating techniques that use light, one stands out for its ability to transform cancer surgery: time-resolved fluorescence.
