Thats good news Chocchip and UCSF is top notch. My best friend who is about 7 years ahead of me on the PC "train ride" is under their care with Dr Peter Carroll. His PC was found by DRE the same as yours. It amazes me that only 40% of men are actually being screened for PC as it is the #2 cause of cancer death (for men) in the US. I just attended the UCSD Prostate Cancer Summit in San Diego last weekend and they are very pro A.S. They stated for those who decide to delay definitive treatment and go on A.S. there is statistically no increase in outcome risk over choosing an immediate intervention (ie radiation, surgery). The issue they (UCSD Medical) stated is that many folks accept A.S. and then dont follow the A.S. protocols (repeat PSA, MRI, biopsy), and fall off the radar only to pop back up years later and find out things changed. Anyway, based on your low PSADT (PSA Doubling Time), low volume and favorable decipher, I think A.S. may be a good way to go for now.
