My dad, Joe, PD 92/89/?? ... has had prostrate for at least the past 10 years, so he was diag. probably in his early 80's. He has been treated with Lupron injections every month, until they had a 3 month injection, and continued with those until Sept last year when the doctor chg'd to Zolodex injection, this is also a 3 month dose. He has had good success with no ill effects from the prostrate cancer. PSI is checked and he's doing well. Of course each case is different. We wish you well in your treatment of choice. Ladye for Joe
