They don't mention their false negative rate, nor any of the rates for competing tech. So we can't say that this device catches the one in X that other machines don't catch. And we can't say that this machine finds 1 in 1,000, where competing machines only finds 1 in 100,000.

In theory early detection is good, but I'm not sure what treatment is available if cells are found this early ad the stress for the other 1,000 people is going to be significant.
