A New Path to Preventing Cancer
A landmark study has discovered a 14-protein blood test that can predict and prevent lung cancer more than 5 years before diagnosis. The study used machine learning and high-throughput proteomics to identify the proteins, which were validated in 8 different cohorts. This breakthrough has significant implications for cancer prevention and could lead to the development of new treatments and therapies.
- ▪A team of over 80 researchers from 4 continents reported on the discovery of a 14-protein blood test for predicting lung cancer.
- ▪The 14-protein signature was validated in 8 different cohorts and outperformed prior lung cancer models based on demographics and smoking history.
- ▪The study found that the 14-protein signature was present on average 5.6 years before participants developed lung cancer.

News and AnalysesA New Path to Preventing CancerA Landmark Study Showing the Way ForwardEric TopolJun 13, 2026218438ShareIn the journal Cell, a team of >80 researchers from 4 continents reported on the discovery of a 14-protein blood test which paved the way for predicting and preventing lung cancer more than 5 years before it would be diagnosed. Current efforts in cancer are largely directed to therapy and early detection, with only a very limited foray to prevention. In a recent Ground Truths, I reviewed the emerging potential for preventive cancer vaccines in people with a known pathogenic mutation (such as Lynch syndrome or BRCA).
