Scientists Find 14-Protein Blood Test Predicts Lung Cancer 5 Years Early, Flags 50% Drug Benefit

Summary
A multinational team led by Charles Swanton identified a 14-protein blood-plasma signature that predicted lung cancer a median 5.1 years before diagnosis.
Using proteomics data from about 48,000 UK Biobank volunteers to train a machine-learning model, researchers then detected more than 75% of 75 later lung-cancer cases in a 12,000-person test set.
Eight additional datasets, including lifelong non-smokers, also showed the signature, which was strongest alongside inflammatory pathways tied to smoking, air pollution, COPD and pulmonary fibrosis.
A retrospective look at the CANTOS trial found 2,300 participants with the signature who received canakinumab had a 50% lower lung-cancer risk, pointing to a possible preventive use for the anti-inflammatory drug.
The finding still needs broader validation and a clinical blood test, while canakinumab's side effects and roughly $73,000 annual US cost could limit any prevention strategy.
A test can predict lung cancer years in advance, but the only known prevention has serious risks. Is this breakthrough a dead end?
Two rival blood tests can now spot lung cancer early. Which one will revolutionize screening, and how soon?
14-Protein Blood Test Predicts Lung Cancer Years Before Diagnosis: A New Era in Early Detection and Prevention
Overview
In June 2026, an international research team published a major breakthrough in Cell: the discovery of a 14-protein blood signature that can predict lung cancer years before clinical diagnosis. Using machine learning on blood samples from over 48,000 people, the researchers showed this signature could identify risk more than five years in advance, offering a crucial window for early intervention. This early detection has the potential to dramatically improve patient outcomes by enabling timely treatment. The discovery marks a significant step toward revolutionizing lung cancer screening and prevention, making it possible to save more lives through earlier and more accurate risk assessment.
