Believe me, I have thought about these questions, and they are very good questions. My understanding is that PSA will continue to reflect cancer activity. In other words, IF the PSA goes down (I know, VERY UNLIKELY) then it LEGITIMATELY reflects the cancer activity. You keep implying that any drop (let's assume due to my new regimen) is just masking an PC increase. From everything I've read, that is NOT TRUE. So, I claim that I will still be getting accuracy with the PSA test. For example, the claim made for XXX (say anti-oxidents) is that it has anti-cancer activity, not that it will mask a rising PSA (note that certain drugs like avodart WILL mask a rising PSA, especially for those who still have a prostate, but even then the urologists claim to be able to adjust for that -- they double the PSA obtained).
By your logic, I should do nothing. Why go to a more heart healthy diet? Why do more exercise? It's the same thing, UNLESS you believe that such substances ARTIFICIALLY lower your PSA, thereby masking the activity. I've seen no such claims, other than your postings. IF that were true, then your point is valid.
Now, in terms of what is causing the drop, I guess I'd have to think more about it when that happens. Most likely I would have no clue and I would just continue doing what I'm doing.
Also, I love your anti-exercise thread. It's a lot of fun. But surely you don't really advocate being a couch potato and really eating poorly (I know you have often advocated a heart-healthy diet and I totally agree with you there). I would assume as you recover more and more that you will just naturally be more active. I HOPE that thread is tongue-in-cheek. It is really very well done!
