A major challenge for cancer surgeons is to determine exactly where a tumor starts and where it ends. Removing too much tissue can impair normal functions, but not taking enough can mean the disease could recur. The “MasSpec Pen,” a handheld device in development, could someday enable surgeons to distinguish between cancerous and healthy tissue with greater certainty in seconds, while in the operating room. Today, researchers report first results of its use in human surgeries.
