AZ guy, I, also, had a post surgery upgrade...not as much as you (I went from G6 on one side to G3+4 in all 4 quadrants). The key for you is to recuperate from the surgery and see what your PSA is in 3 months. Seriously, 3 months. Your doc may do a PSA at 6 weeks, but it's not definitive till 3 months. In the meantime, walk, eat well, do your kegals, and get back in shape.
Halbet, did you change labs between 8/30/16 and <0.04 and 2/15/17: <0.006? Of course, I realize <.04 could also be < .006, but that is possibly a huge drop, depending on whet the actual <.04 was, which could have been .03(or of course much lower). Or maybe your doc or other lab simply got new machines. But man, that is a low #!
AZ Guy, lets face it, we are dealing with possibly microscopic cancer cells(unless the needle got lucky and happened to stick right into the middle of a mass/tumor), and it is not difficult to miss a bunch of higher Gleason cells. We are probably lucky that they manage to more often than not hit the bad areas with our highest Gleason, or even hit a cancerous spot at all. Some of us are down graded, but not a few of us are up graded. The Bx is just a crap shoot, ore or less. On the bright side, one reason(certainly not the only) a bunch of us decide to have the surgery is to get that path report, just in case of a situation like yours exists. You and I both got news we didn't want, but at least we know. Hang in there Brother!
