HEALTH DESK: New Blood Test Can Detect Even One Cancer Cell
Researchers in the UK have unveiled a promising new blood test capable of spotting even a single lung cancer cell, potentially transforming how the disease is detected and managed.
The approach uses advanced infrared technology to identify circulating tumor cells, offering a simpler and more affordable alternative to current methods.
This development could lead to earlier diagnoses and better monitoring of treatment progress.
How the Technology Works
The method relies on Fourier Transform Infrared (FT-IR) microspectroscopy, where infrared light is directed at a blood sample on a standard glass slide.
Cancer cells absorb the light differently, producing a unique chemical fingerprint that computer analysis can detect quickly.
Unlike many existing techniques, it requires no complex preparation and works with equipment already common in pathology labs.
Key Advantages Over Existing Tests
Experts highlight several benefits:
- High sensitivity to detect individual cancer cells among thousands of healthy ones.
- Faster results with minimal invasiveness compared to biopsies.
- Lower costs, making it more accessible for widespread use.
The test was validated using a sample from a lung cancer patient, confirming its accuracy through independent checks.
Team Behind the Breakthrough
The collaborative effort involved specialists from University Hospitals of North Midlands NHS Trust, Keele University, and Loughborough University.
Lead researcher Professor Josep Sulé-Suso emphasized the potential for real-time monitoring and personalized care.
Future applications may extend to other cancer types, building on prior feasibility studies.
Publication and Next Steps
Findings appeared in the journal Applied Spectroscopy, marking a step forward from earlier proof-of-concept work.
The team plans larger clinical trials to refine the technique and integrate it into routine NHS pathways.
Support came from local charities and university resources, underscoring community-driven innovation in healthcare.
