Spectroscopy during Surgery Could Catch Tumors
A pen-like device that collects both fluorescence and Raman spectra could enable more accurate surgeries to remove tumors.

A device shaped like a pen collects both fluorescence and Raman spectra from tissue; it can detect cancerous tissue at the edges of tumors and satellite tumors during surgery. This could guide surgeons for more accurate surgery to remove tumors. Removing all the cancer during surgery is the single most important predictor of patient survival for almost all solid tumors, but the difference between cancerous and benign tissue isn't always obvious to the eye.
