A Japanese team has developed a reagent that can make cancer cells glow and become visible to the naked eye, an advance that could help surgeons more accurately distinguish between cancerous and healthy tissue, the medical journal Science Translational Medicine reported Wednesday.

Within minutes, the sprayed reagent, developed by Yasuteru Urano, a chemical biology professor at the University of Tokyo, and Hisataka Kobayashi, chief scientist at the U.S. National Institutes of Health, can highlight carcinoma smaller than 1 mm, which magnetic resonance imaging and other tools cannot detect.
