Glowing ‘Tumor Paint’ Shows Surgeons Where to Cut
8th April 2015
Brain surgery is notoriously complicated. Before surgeons go in to remove a tumor, they study the size and location of the tumor. But once they’re in, they have to rely on their fingers and eyes to distinguish tumor cells from healthy brain cells. Now researchers have developed a “paint” that can be injected into a patient’s veins to make tumor cells glow. After a number of successful studies in mice and dogs, the paint is now being tested in humans in California.
