We get lots of posts like yours. Yes loads of people go in to panic mode. STOP PANICKING. From where you are now you probably have about a 10% chance of getting a positive diagnosis of clinically significant prostate cancer. we have had PSAs in the 30s even the 80s which have come back clear.
The only way you can know for certain is have all the tests. Even if you do get a positive diagnosis it is very treatable.
Please keep us informed, particularly if you get the all clear. I want to keep a track of all these negative diagnosis to reassure the next person who comes along in a panic.
