Hello Charlie,
I am in a kind of similar position as you. I had surgery over four years ago: my initial PSA after surgery was 0.008.........three months after it was 0.03.........and after over four years our cancer clinic took over at 0.53.
I did have a positive margin after surgery.
I am currently on Lupron and Casodex with a tentative radiation date of August.
I fully agree with what Thoosier has said.
Good luck....................Stan.
