Hi Bill and those who responded to my psa question. Thanks for taking the time to respond. Just had another biopsy--negative. Every three months I have the psa test, ultrasound and digital exam. Every 3-6 months a biopsy. In fact, this last time the urologist took a sample of eight snips instead of the more usual six. He figures that at this rate we'll soon have removed the whole prostate on the installment plan. Again, thanks all. Stan
