Sam,
I would recommend that you go to the website www.yananow.net. When you enter the website click on Mentor Experiences. Located here by type of treatment are the stories of men that have dealt and are dealing with prostate cancer. The more advanced cases can be found under the hormone treatment. There are stories of men here that have had PSA's like your father and some higher that have survived for many years. These may be helpful. Just a warning some of the stories are graphic in language and detail the side effects of treatment but they do tell it like it is.
