Lung Cancer Breathalyzer Test

Lung Cancer Breathalyzer Test

Diagnose lung cancer in one simple breath…

Researchers at the Russell Berrie Nanotechnology Institute in Haifa, Israel, have developed a device that is able to detect lung cancer from one single breath.

The sensor, made from nanoparticles, can distinguish between the breath of those with lung cancer from those without. Furthermore, the sensing technology does not require the exhalation to be pre-treated in any way – existing tests required the biomakers to be preconcentrated to improve detection.

The result, is a breath test that is simple affordable and portable.

Lead author Hossam Haick said:

“We demonstrated that our device has a potential not only to distinguish lung cancer patients from healthy controls but also to identify different types of primary lung cancer,”

The device works my measuring the levels of volatile organic compounds expelled in the breath. In patients with lung cancer, VOCs range from 10 to 100 parts per billion whereas healthy humans only expel between 1 to 20 parts per billion.

Researchers noted that there was “no overlap of the lung cancer and healthy patterns,” even though there is a 10-part overlap in the range of VOCs.

The findings, reported in Nature Nanotechnology, could help screen for and diagnose lung cancer so quickly and affordably that the sensor has the potential to save millions of lives a year.

Haick went on to explain that diagnosing lung cancer using this method may be the first of many applications:

“The potential exists for using the proposed technology to diagnose other conditions and diseases, which could mean additional cost reductions and enhanced possibilities to save lives,” Haick says.
