He may have meant the jump from 3.9 to 4.6 or 4.7 was a big deal in six months. Like I said, this discussion is a little foggy in recollection.
I have recalled it now because with the suggestions for waiting it gets me wondering what's the natural variation in PSA scores versus significant "big deals"? And over what periods of time with what frequency?
My delta was certainly a good predictor of ca, but I just wondered what would have been a "natural" variation had I waited versus "man, this is becoming a bigger deal"?
Considering the stories I hear about everyone needing a good trend of PSA scores before even making a decision to biopsy, I just wanted to know if anyone had a sense of the numbers considering all of us unique. Just what kind of variation is normal and what isn't?
I am pretty sure that is what the doc was talking about
. A rise in excess of 0.75 in a year is a trigger that sets off alarm bells and is suspicious even when the PSA is fairly low. As your PSA increase was over six months it equates to a rise of at least 1.4 in a year.
