At first glance, the idea seems absurd, but the research of an Israeli institute could not be more serious. Indeed, it is possible to detect cancer in a patient based on their breath. Explanations.
This practice is not really new, but now it turns out to be reliable enough to be applied widely in the medical world. The study published on December 21, 2016 in the journal American Chemical Society gives full details.
Israeli engineers from the Technion Institute have developed a sensor capable of knowing more about a patient’s state of health. It is a device embedding a chip which makes it possible to detect several diseases simultaneously. Composed among other things of gold nanoparticles and carbon nanotubes, it is able to establish a calibration (and a quantification) of the organic molecules exhaled, in other words what results from our breath!
The researchers carried out a battery of tests on 1404 volunteers (sick and healthy people) and a total of 2808 breath samples were taken. The results made it possible to compile a directory of 17 Volatile Organic Compounds (VOCs).
What is very interesting is that each of these VOCs corresponds to a particular disease representing a kind of « breath imprint » characterized by 13 organic molecules present in our breath in a natural way. Among the cancers identified using this process, we find cancers of the prostate, lungs, bladder, ovaries and colon-rectum as well as kidney and stomach.
The device developed is directed by an artificial intelligence acting as an operator who also compares the results of analyzes in order to provide a detailed conclusion. According to the researchers, the accuracy rate is 86%, which is remarkable, especially since the test only lasts for one breath! This technology seems to be welcome when in France alone, 150,000 deaths were caused by cancer in 2015.
