Dr. Peter Mazzone and his team invented a senzor that will help diagnozing lung cancer in early stadium (when it can be still treated successfully), using cheap and non-invasive method. And it diagnoses it just by examining breath.
Rather than determine the exact chemicals and their concentrations, this sensor changes color depending on the pattern of chemicals. The device is about the size of a nickel and has 36 dots, each made up of a different chemical.
“The color of that dot changes based on what chemicals are absorbed into it,” Mazzone explained. “So, the pattern of chemicals in the breath is represented by patterns of color changes on the sensor.”
A type of X-ray called spiral computed tomography or CT can find lung cancer early, but it is expensive and also finds non-cancerous lesions that are expensive and risky to test.

hello Dejan, this is a very important step for medicine. I hope that it’ll be followed by others.

Sure it is, and I presume that Dr. Mazzone is Italian, because of his surname. Well, it seems that you Italians are one very intelligent nation!
