Glow-in-the-Dark dyes may help surgeons remove more brain tumor

This study looked back at medical records of 41 patients who had surgery for aggressive brain tumors (high-grade gliomas). Some surgeries used fluorescent dyes that make tumor tissue glow, helping surgeons tell it apart from healthy brain. The goal was to see if using these dyes leads to more complete tumor removal, as confirmed by MRI scans. The study did not test a new treatment, but rather reviewed past cases to learn how well these dyes work.
