Thanks again to all for your replies. I think Barry's suggestion of an MRI is wise. However, a CAT SCAN is out of the question as they rely on too much radiation. I'm glad to hear that someone has survived for 10 years and counting on hormone therapy, and the advice on seeing an oncologist to discuss my options will certainly be considered.
I know that diet and supplement has not been scientifically proven to be effective however I am certain that it has helped me survive thus far. I take monthly PSA tests in order to see how my diet is affecting the readings. Sugar and fats and any processed foods shoots my PSA up. And believe it or not, I have brought my PSA levels down a bit by just maintaining a strict vegetables and grains diet. However, this is hard and I tend to "treat" myself once in awhile and pay a price for it. Without a doubt, diet and certain supplements has extended my life thus far.
That said, it is time to consider other options. Thank you all.
