A domestic dog can accurately detect the early presence of lung cancer bysniffing patients ’ breathing place , doctors in Germany say . While researchers have know for some time that dogs can sniff out the telling sign of other forms of cancer , this is the first cogitation that proves dog can dependably smell this special kind .
This is a breakthrough for lung cancer researcher who have been trying to figure out if there are specific volatile organic compounds consort with the bearing of the disease . The Canis familiaris study suggest that there are .
Researchers at Schillerhoehe Hospital in Germany worked with specially trained Canis familiaris who were asked to smell the breath of 220 voluntary . The radical include healthy patients , as well as mass with lung genus Cancer and continuing obstructive pulmonary disease . The pawl aright identified 71 positive lung Crab samples out of a potential 100 , the research worker drop a line in the European Respiratory Journal . They also correctly key 372 non - cancerous sample distribution out of a potential 400 .
What ’s interesting about this is that the Canis familiaris were able to detect cancer even in the bearing of other element , like tobacco plant locoweed and COPD . Current lab tests for lung Crab ca n’t do this . This suggests that there is indeed a VOC associated directly with lung Cancer the Crab , which can be detected – at least by a dog – even in the bearing of other compounds .
VOCs are emit from the surface of cell as they undergo tumour - induced gene and protein change . Identifying the VOCs that sure jail cell make can go a long way toward other diagnosis , when a CAT scan might not be capable to detect anything .
Other researchers have been working on lab chips that can make the same diagnosing , without using dog . Israeli researchers reported last year that theirgold nanoparticle e - nosecould differentiate among lung , breast , prostate gland and colon cancer – by differentiating among the VOCs .
But as we ’ve seen before , sometimes dog are but the best sniffing technology out there . TheDefense Department figured this outafter spending billions of dollar on research . This new study suggests that doctors may be learning the same thing .
