Scientists Find Blood Proteins That Predict Lung Cancer 5 Years Early, Flagging Drug Prevention Potential

Summary
More than 80 researchers across four continents identified blood proteins that predicted lung cancer more than five years before diagnosis, pointing to a possible way to spot high-risk patients earlier.
The same study linked those elevated protein levels to inflammation and found early evidence that an existing anti-inflammatory drug could significantly cut lung cancer risk in people with that biomarker pattern.
Cell published the findings on Thursday, but researchers said a patient-ready test still needs further validation and the drug signal must be confirmed in a randomized trial.
Lung cancer remains the world's most commonly diagnosed cancer and kills more people than any other cancer, with fewer than one-third of patients surviving beyond five years.
Outside experts called the work a promising step toward prevention, an area that has lagged even as screening, targeted drugs and immunotherapies have improved earlier detection and treatment.
If a blood test can predict lung cancer, could a common anti-inflammatory pill stop it before it even starts?
This new cancer blood test shows promise, but after other major trials failed, what makes this one different?
AI Blood Tests Can Predict Lung Cancer Years Before Diagnosis—A New Era for Early Detection and Prevention
Overview
Recent research marks a major step forward in lung cancer prevention by identifying specific blood proteins that signal an elevated risk years before diagnosis. Scientists achieved this by integrating genomic and proteomic data, uncovering new susceptibility loci and protein markers in blood plasma. These candidate biomarkers can help distinguish individuals at risk long before symptoms appear, paving the way for more precise risk assessment. While the findings are still exploratory and do not yet prove a direct cause, they lay essential groundwork for future studies to investigate these biological mechanisms and develop early detection strategies.
