A silicon chip the size of a business card could soon speed cancer diagnoses, track treatment more closely, and discover earlier signs of recurrences.
Researchers from Massachusetts General Hospital have developed a better technique for collecting and measuring the cells that escape from tumors and travel through the bloodstream, spreading cancer from one part of the body to another.
These so-called circulating tumor cells have been difficult to study, and little is known about them - but tracking them down has been a major goal of scientific research for decades.
Technology these days!
