Early signs of lung cancer could be diagnosed using a simple blood test following a new discovery by scientists at the University of York. Early detection of lung cancer has been shown to save lives, but available methods for screening at-risk people are either too costly or involve invasive procedures.
The latest findings mean that a simple blood test could now be developed. The scientists say an altered form of a protein called Ciz1 is present in lung cancers, even when they are at a very early stage. This means by looking for variant Ciz1 in the blood scientists can pick out people who have small tumours in their lungs, without the need to take a biopsy or undergo surgery.
