This 3-D printed pen lets surgeons detect cancer in 10 seconds

A team of scientists and engineers from the University of Texas at Austin may have figured out a fast and accurate way to diagnose tumors using a pen-sized device.

The MasSpec Pen can detect cancer of the breast, thyroid, lung, ovaries and brain with 96.5 percent accuracy, based on an initial test of over 250 patient tissue samples, said Livia Eberlin, an assistant professor of chemistry and the study’s designer.
