UNC researchers explore light-based approach to safer cancer treatment

At the University of North Carolina, researchers are asking whether light — one of nature's most elemental forces — might offer medicine a more precise and humane path through one of humanity's most feared diseases. Building on decades of phototherapy knowledge, the team is investigating how controlled wavelengths of light could target malignant cells while sparing the healthy tissue that conventional treatments so often damage. It is a pursuit that sits at the boundary of physics and compassion, where the goal is not merely to cure, but to preserve the life being saved.
