I could use some insight and wisdom from your experience. I am 60 years old. about four years ago my PSA was at 4. A biopsy was ordered and found to be negative. Praise God! – I have been taking 5mg of Terazasin sense then and my PSA went to 1. Six months ago my PSA was 1.5 and last night my doctor (Kaiser), called and said that the test results from a recent physical showed my PSA to be 4.5. Such a big jump concerns him, so now I go the Urologist and he will o doubt recommend another biopsy. I know your not doctors, but you have something better, experience. What do you think?
