Here is what I would like to see...

Take the following group of samples and test a percentage with RECAF. You could see the data evolve over several years and see if RECAF could have helped when combined with the PSA test.

"In both, participants were randomly assigned to be screened — or not — with the PSA test, whose initials stand for prostate-specific antigen. In each study, the two groups were followed for more than a decade while researchers counted deaths from prostate cancer, asking whether screening made a difference.

The European data involved a consortium of studies with different designs. Taken together, the studies found that screening was associated with a 20 percent relative reduction in the prostate cancer death rate. But the number of lives saved was small — seven fewer prostate cancer deaths for every 10,000 men screened and followed for nine years."
