Scientists at the Israel Institute of Technology (Technion) have announced a way to spot certain cancers with a simple breath test.
Using eighty-four volunteers, they were able to develop a device, named Nano Artificial Nose or Na-Nose, to detect the presence of head and neck cancers.
The researchers were also able to spot the difference, analysing breath alone, or people with and without lung cancer.
The study, published in the Journal of Cancer Research, suggests that microchemical changes in a body subject to cancer make breath testing an ideal way to diagnose the illness.
This is especially when cancers within the head or neck can be difficulty to diagnose and treat, making spotting them at an early stage crucial.
However, researchers and cancer charity groups have warned that even if the test is reliable and commercially viable, it will still require a few more years of testing before it is likely to be found in local doctor surgeries for screening purposes.
