Researchers in Israel have developed a device that can detect cancer by analysing a patient’s breath.
The device uses sensors involving gold nanoparticles to detect chemicals that are released by cancerous tumours and exhaled.
In a study of 177 individuals, the device was able to detect not only whether participants were healthy or had cancer, but was able to differentiate between breast, lung, prostate or bowel cancer.
Professor Abraham Kuten of the Technion Israel Institute of Technology, where the research was carried out, said the study shows that an ‘electronic nose’ can distinguish between healthy and malignant breath.
“If we can confirm these initial results in large-scale studies, this new technology could become a simple tool for early diagnosis of cancer, along with imaging,” Kuten said.
