Ted has told me about some of the most terrifying cases are the exact opposite these guys that show up with a low PSA with a very low PSA a PSA of 1.9 those are worse and for sure uh rampant metastatic disease right right right and that's the thing you get some of these really poorly differentiated cancer that no longer resemble their prostate progenitor cells and they just they're very hard to monitor and a lot of them even don't even show up on a PSMA PET scan
