'Electronic nose' can smell cancer on patients' breath
An ‘electronic nose’ has been developed that can sniff out cancer in patients' breath.
The device can distinguish between people with the disease and healthy individuals.
Scientists believe it may be very useful for identifying patients with head and neck cancers which are often diagnosed late.
The Israeli researchers collected breath samples from 82 people who either had head and neck cancer, lung cancer, or were cancer-free.
Professor Hossam Haick, from the Technion Israel Institute of Technology, said: “We've shown a simple ‘breath test' can spot the patterns of molecules which are found in head and neck patients in this study.”
