Fluid Biopsy' Could Transform Cancer Treatment by Making Tumour Cells Glow in the Dark

Cancer treatment could be transformed by a new 'fluid biopsy' technique that spotlights tumour cells in the bloodstream, scientists say.

Researchers in the U.S. have developed a way of attaching fluorescent 'tags' to cancer cell proteins, making them glow under special light conditions.

The technique - successfully tested on patients with breast, prostate and pancreatic cancer - paves the way to 'real time' assessment, therefore speeding up treatment of disease.
