Scientists have developed a “pen” that can help surgeons identify cancer cells within 10 seconds. The tool could one day be used during surgeries to quickly determine what tissue should be cut in order to remove tumors completely.
The device, called MasSpec Pen, isn’t perfect yet, however; it can distinguish between cancerous and healthy tissue with about 96 percent accuracy. But the team behind the device, described this week in the journal Science Translational Medicine, hope
