Lung cancer screening has always been expensive, but a simple blood test that detects lipids associated with tumours may offer a cheaper alternative
A blood test that can detect lung cancer before people get symptoms may save lives by allowing early treatment.
Catching lung cancer early is difficult because we don’t have any cheap, simple ways to screen for it. Chest CT scans can be used to look for tumours in the lungs, but they are expensive, expose people to radiation and can sometimes make false detections.
The 13 individuals who were found to have lung cancer – mostly early stage – were treated by surgically removing their tumours.A benefit of the test is that it takes less than 90 minutes to complete, from taking a person’s blood to running it through a mass spectrometry machine to measure lipid levels and crunching the data, says Wang.
