Jim, guys who participate here on the HW forum are always glad to learn that they've in some way helped someone like you find his way through the maze of prostate cancer diagnosis and treatment.
Congratulations to you for monitoring your PSA level and finding that Gleason 9 cancer early. Here's hoping the adjuvant radiation will do the trick and kill off any cancer cells that may have escaped via that positive margin. Let us know how it goes.
Best of luck to you, and I hope you hang around and stay in touch.
