Scientists' AI blood test detects cancer using infrared light pulses

Scientists have developed a new blood test using AI and infrared light pulses. It identifies cancer's molecular "fingerprints" in blood plasma. This method detected lung cancer with up to 81% accuracy in a study published on April 9. The AI model analyzes how molecules in blood plasma respond to infrared light, creating a unique "fingerprint." This differs between individuals with and without cancer. The test is in early stages, aiming for earlier, less invasive cancer detection. The study tested the model on lung, prostate, breast, and bladder cancers. While successful for lung cancer, accuracy for other cancers was lower. Researchers plan to expand the testing with more data to improve overall accuracy.
