A glowing dye that sticks to cancer cells gives surgeons a 'second pair of eyes', according to experts at the University of Oxford. The dye clings to prostate cancer cells and then starts glowing when illuminated during surgery. This means doctors can remove more of the cancer during the operation and reduces the chance of it coming back. Although the dye currently identifies prostate cancer, it could be adapted for other forms of the disease.
In an initial study, 23 men with prostate cancer were injected with the dye before undergoing surgery to remove their prostates. The fluorescent dye showed the cancer cells and where they had spread into other tissues, such as the pelvis and lymph nodes. A special imaging system shone a light on the prostate and nearby regions, making the cancer cells glow. Read more from Sky News:Electric headset for treating depression recommendedE.
