Lung cancer: New blood test can find cancer one cell at a time

Researchers have developed a groundbreaking blood test using Fourier Transform Infrared (FT-IR) microspectroscopy to detect a single lung cancer cell. This innovative technique identifies the unique chemical fingerprint of cancer cells, offering potential for earlier diagnoses, personalized treatments, and fewer invasive procedures. The findings, published in Applied Spectroscopy, could extend to other cancer types.
