Lawrence True: Yeah, so my thoughts are really based on the sampling issue and... I hear us talking about two things: prostate cancer, the radical prostate, and the biopsy. So this is really focused on the biopsy, and that is the third one here. This is from Lisa Newcomb, who manages our Canary Active Surveillance project. I asked her how often Grade Group 1 cancer is followed by progression in subsequent biopsies, or actually in the prostatectomy. Here you have the data that she sent: six positive nodes, six regional mets, nine distant mets. 21 patients out of about, I think it's now, what, 2,000-

2,000 or so. And then the second is that I asked her how often there's a second biopsy that's Grade Group 1 after. Could you increase the frequency with which you can say with confidence, the cancer, the Grade Group 1, and basically, you can't. And again, this is just focused on biopsies.
