What stands out to me is how cancer therapy keeps moving from broad destruction (chemo/radiation) toward increasingly precise identification of malignant cells. The challenge no longer seems to be "can we kill cancer cells?" but "can we reliably identify only cancer cells and reach all of them?" This paper looks like another step in that direction.

I'm not sure what this comment means - we could always kill cancer cells, and the challenge has always been "how can we ONLY kill the cancer?" We've been burning cancer, cutting cancer out, and drugging cancer cells for decades or centuries depending on the method. What is changing is not the type of challenge, but the precision of our tools - and even then, it remains to be seen if we actually can get the precision while improving the lives of the patients.
