New laser device detects diseases by leaps and bounds

Researchers from the University of Adelaide detect a new device technology works (optical dog nose), which can detect the presence of cancer, inflammation and diabetes very quickly.
The device and the use of special laser technique to measure gaseous molecular level, during the metabolic processes in the body, and that a change in the levels appear when there is a defect or disease.

Therefore, this device will be useful in the detection of many diseases such as diabetes and cancers of the digestive system and lung disease and asthma, before the appearance of any external symptoms. 
And refers James Anstey, a researcher at the Institute (IPA) for Science and Photonics at the University sensor that this system uses laser light to Easter and invisible particles that are present in the sample.
