We are very similar in level of diagnosis post surgery. As you can see by my signature, my 2 month post surgical PSA was .01, but then at 5 months I'm .08. With those ultra-sensitive tests, the .08 is significant, but not showing biochemical reoccurance, which many experts say is .2. However, since I had positive margins, my surgeon and oncologist wanted me to think about further treatment back at my two month mark. There are a couple of studies showing that additional RT can decrease the possibility of reoccurance. While I have been contemplating it since March, my .08 solidified my mind. Like you, I'm 57, and surviving a long time is my first priority. Therefore, I'm starting adjuvant RT in late August. With that, there is additional controversy on whether to have hormone therapy along with it. My situation is right inbetween yea or nea. Both my surgeon and oncologist recommended it, and work by a Dr. Robert Lee also agree. Therefore, I had my first Zoladex injection yesterday. Since my first diagnosis, I have approached this disease aggressively. I realize that there will be some side effects from further treatments, but I'll work through that with the final goal of staying cancer free for as long as possible.
My recommendation for you, is to wait until you get your post surgical PSA's before making any decision. Do a lot of reading - Google searches work well - and hope for all zeros.
