1 of 1B - [pre-cancerous cell] to [normal cell]

1 of 1M - [false-positive cell] to [cells tested]

So, given my poor stats background and guessing what that means...

1B - cells tested

1k - false-positive cells

1 - pre-cancerous cell

-->

20T - ALL cells tested

20M - false-postive cells

20k - pre-cancerous cells

So one in one thousand positive results is legitimate. How is this tool remotely useful?

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.
