(CNN)A breathalyzer designed to detect multiple cancers early is being tested in the UK.
Several illnesses are known to create signature smells from the body, including typhoid fever reported to smell like baked bread and the aroma of acetone, said to be similar to rotten apples, on the breath of diabetics. Recent research has also shown that a person's breath could also indicate the presence of cancer.
To test this theory, Cancer Research UK have launched a two-year trial into a clinical device, called the Breath Biopsy, to find out if exhaled airborne molecules can be useful for cancer detection.
In the body's normal metabolic processes, molecules called volatile organic compounds (VOCs) are produced. It's thought that cancer can create a different pattern of VOCs, which researchers hope to identify using the device. "Our goal is, can we spot these subtle differences?," Billy Boyle, co-founder and CEO at Owlstone Medical which developed the device, told CNN.
The trial, which is being run by the Cancer Research UK Cambridge Centre, is recruiting u
