The study, led by University College London and the Francis Crick Institute, analysed blood samples from more than 48,000 people. Researchers said the protein signature reflects inflammation in the lungs and could help support future prevention efforts.

Researchers said the findings support the theory that some age-related diseases share a common inflammatory state before symptoms appear. According to Prof Charles Swanton of University College London, the protein signature could eventually help predict and prevent not only lung cancer but also other lung diseases. Further research will be needed before the approach can be used in clinical practice.
