It seems surprising that the laser has such selective activity on CTCs versus healthy cells. Why are these cells so much more absorbtive? Is this specific to melanoma CTCs (more pigment)?
I also wonder how they did this measurement. Seems like you'd need to take pre- and post-laser measurements of healthy and CTC counts in the bloodstream to have high confidence that it is disproportionately damaging CTCs. To what extent does this damage healthy cells?
- nvusuvu 7y agoEven if it damaged/killed a small percentage of healthy cells, as long as it kills a much higher percentage of CTCs, hook me up. Good cells are replenished. So are the bad ones. Its an arms race!

- codesnik 7y agoWow. That sounded like something from a comic book.
