Summary

This study compares two types of light used during bladder cancer surgery: standard white light and blue light, which makes cancer cells glow. The goal is to see if blue light helps surgeons remove more cancer and lowers the chance of the cancer coming back. About 200 adults with high-risk non-muscle invasive bladder cancer will be randomly assigned to one of the two methods. Researchers will check for leftover cancer using standard tests and a urine test that looks for tiny traces of cancer DNA.
