I know statistically you guys are right. I also know that sometimes there is residual prostate tissue that is not removed during the surgery, and may be able to produce small amounts PSA.
All that being said, if there was no value in knowing PSA to the .01, I doubt there would be any reason to do those tests. It is easy for us to say, don't worry, it's less than .1. Since .5 is commonly acknowledged here as the decision point for reoccurence, why not say less than .5 is zero, or of no consequence?
I agree there is no reason to take any action. But, in my own PSA's, I am certainly going to look carefully at the next PSA is 90 days. What I am looking for is a trend. I have decided that 3 increases in PSA, no matter whether it is .01 increments or .1 increments, I say a trend is a trend.
I guess what I'm saying is that I think we are a little too quick to dismiss these small increases. I know that in a large number of cases, they do go back down. I still say it is like a yellow warning light on the dash. It goes off for a reason.
