The video in the link you posted, stresses the importance of distinguishing between cancer cells that will metastasize, and those that will not, so as to not unnecessarily subject a patient to treatment when none is needed.
I'm not sure how that relates to Flynn's technology, as it is simply much more accurate in detecting cancer cells than currently available screening methods, but, to my knowledge, it does nothing to help distinguish between cancer cells which may metastasize, and those that won't.
Please correct me if I am wrong.
