'Immune fog' may indicate lung cancer risk long before diagnosis

3w ago October 9, 2026 1 min read 📰 Medical Xpress
📋 Key Takeaway

Researchers at University College London have identified a phenomenon termed 'immune fog' that may hinder the immune system's ability to detect lung cancer years before it manifests. They have developed prototype blood tests to track this signal and have found ways to reverse it using medication. This research could have implications for cancer detection and treatment in Iran, where healthcare advancements are critical.

🔍 Quick Context Guide
💡 Bottom Line: The identification of 'immune fog' could revolutionize lung cancer detection and treatment, with significant implications for healthcare in Iran and beyond.
