Breath test 'could help detect cancers earlier'

Cancer could soon be picked up through a simple breath test, after researchers launched a clinical trial to see whether molecules in the mouth could identify disease.

In tests run by Cancer Research UK, breath samples from 1,500 people will be collected in the hope that odorous molecules called volatile organic compounds (VOCs) can be detected.

All cells produce VOCs through their normal day-to-day operation, but if their metabolism changes, such as in cancer, they release a different pattern.

If the trial is successful, it would mean that cancer could be spotted quickly before it has spread, when it is easier to treat and when chances of survival are greatest.
