The document discusses a new technology that uses lasers to detect cancer cells in the bloodstream. This early cancer detection system works by identifying clusters of circulating tumor cells that have shed from primary tumors into the bloodstream. If successful in clinical trials, this laser-based system could provide a simple blood test to detect many types of cancer at earlier stages than current methods.
