NEW YORK (360Dx) – A group of researchers led by the University of Michigan has developed a wearable device that can continually collect circulating tumor cells (CTCs) in an individual's bloodstream and monitor the amount of cancer cells over time in the person.

While only tested in canine models at this point, the researchers believe that clinicians could potentially use the microfluidic chip-based system attached to a vein to detect cases of cancer and track the number of cancer cells in patients with minimal residual disease and relapse.
