Breast cancer is the most common cancer today. It is mandatory to detect it at an early stage. GratXray is currently building a new medical device to provide true volumetric 3D approach and more precise breast tumor detection without need of contrast agents. Here is a new medical device with a more precise tumor detection. The breast can be measured without compression, massively improving patient comfort. GratXray is a spin-off at ETH Zurich Switzerland. Watch this interview with Dr. Martin Stauber, a scientist and entrepreneur, bringing innovative research to the market.
