    Fluorescent Marker Could Help Surgeons Remove Brain Cancer

    They’re lighting the way. A recent British trial involving 99 patients with suspected glioma, the most common form of brain cancer, found that a chemical compound called 5-aminolevulinic acid accumulates in fast-growing, high-grade cancer cells — and glows pink when exposed to light. The glowing marker allows surgeons to more accurately identify and remove as many cancer cells as possible while avoiding healthy brain tissue. Researchers hope the development will extend glioma patient survival, which is currently “often measured in months rather than years.”
