Israeli researchers develop faster, cheaper blood test for lung cancer detection

Lung cancer remains the world's deadliest malignancy in part because the tools we use to find it are blunt instruments — CT scans that raise alarms as often as they resolve them. Researchers at Tel Aviv University have now described a blood test that reads the chemical fingerprint of a tumor using light rather than genetic sequencing, achieving high accuracy at a fraction of the cost of existing methods. The test, published in Nature Precision Oncology, does not replace the hard work of clinical validation ahead, but it gestures toward a world where a sixty-dollar vial of blood might spare a p
