My father had very similar prognosis and he did very well with brachytherapy. I'm hopeful that you father will respond well. Good luck with the treatment and please do keep us posted on his progress.
I am age 47 - Father, Paternal Uncle and Maternal Grandfather had/have Prostate Cancer.
Father 74 years old, PSA = 10.6 Gleason = 5 + 5 = 10 (very aggressive) and high involvement in all cores. Seed therapy is the only option. Father died cancer free.
06/04/08 - At physical DRE normal, PSA test returns 4.4
06/20/08 - First Urologist visit. DRE and ultrasound finds nothing conclusive. Doctor says biopsy is the only safe way to go. Prostate volume is 40 grams.
07/11/08 - PSA test returns 4.1. Scheduled the Stereotactic Transperineal Prostate Biopsy for 7/21
07/21/08 - Had the biopsy. Not so bad but sore on day 2. Back to work tomorrow
