Alan,
It may not be as counter-intuitive as you might first think. The way my very limited understanding of the way radiation works, it seems the radiation damages the DNA in the cancer cells. It does not kill the cells. It is not until the cells split (mitosis) that they actually die. Therefore, if a person has rapidly splitting cells (hence, a more aggressive cancer) his cells will die quicker and he will reach nadir faster.
For someone with cells splitting more slowly (a less aggressive cancer), it takes longer for the cell population to die off and nadir to be reached.
If all cancer is killed, it doesn't matter in either event. But, if any cells remain, obviously the less aggressive variety is preferable. So, a man with a longer time to nadir may be more likely to die with the disease than to die of the disease.

Yes. If you notice, I only waited one moth after I hit 7.5 for my next PSA. I decided if it got to 10, I was going to see Dr. Amato. Fortunately, it headed back down.
Even though I was not treated at RCOG, my doc used the same protocol. So, I joined an RCOG group on Yahoo. They have a database where about 60 men have recorded their PSA readings from 6 months out to as much as 12 years. This was incredibly helpful to me to see the wide variety and magnitudes of bounces. It really helped me make a couple of good decisions. It is a shame data like this isn't available in everyone's circumstances.

It kinda makes you wonder how many have jumped the gun and started on ADT and then think ADT is holding the bastard at bay when, in reality, maybe the bastard has already left the building.
Finally, let me say that, while I haven't written very much here over the last five years, I have read almost everything you and others have written and I really appreciate everything you all contribute. It is amazingly helpful.
