A breath test can successfully pick up lung cancer with "moderate accuracy" even in the early stages, reveals research published ahead of print in Thorax. It could revolutionise the way cancer is detected and potentially save lives, say the authors.

Metabolic changes in lung cancer cells cause changes in the production and processing of volatile organic compounds, which are then breathed out. The researchers used the colour sensor to test the breath of 122 people with different types of respiratory disease, and 21 healthy people.
