It’s probably a little bit of both. At .2 there may not be any cancer, I know someone who has had multiple metastasis they’re at .2 and their doctor gives them PSMA pet scans every three months. This is the case where the doctor is trying to catch the metastasis when they start showing up. This is the sort of thing that Scholtz believes in.

If somebody’s PSA is at .2 that means that their prostate cancer is not producing a lot of PSA. That would be more likely due to Small metastasis that aren’t producing much or nothing is there, and that’s just a lot below what a normal male PSA should be.

Unfortunately, there’s no easy way to figure out whether or not there are metastasis. A better option would be a PSE test to see if there’s actually something to scan.
