Breath test to spot stomach cancer: Study

LONDON: Scientists have developed a new type of breath test to diagnose stomach cancers - with an accuracy rate of over 90%.

The new test works by detecting biomarkers - a chemical profile that is associated with specific stomach complaints or types of cancer - in the air people exhale. Scientists from Israel and China took breath samples from 130 patients with a range of different stomach complaints as well as those with stomach cancers.

Scientists found that nanomaterial sensors had over a 90% success rate at differentiating between stomach cancers and more benign conditions. The nanomaterial sensors were also more than 90% accurate at detecting the difference between early and late stage gastric cancers. The researchers hope the breath test could be used as an alternative to endoscopies, an accurate but more invasive procedure.
