This is another place where the lizajane charts can come in handy. I have read that it is the rate of change of PSA that istelling, not the absolute numbers. All men's psa goes up over the years, it's just that if the rate of going up changes, doctors get alert.

So if you chart them, assuming that the first test, which you just called 2003, was in feb, it would look like this:

8/03.............8/06.............2/07.............5/07.........................8/07
0.89........... 2.51............. 2.69.............2.9............................3. 38

.....................60%.............34%......... 37%......................... 60%

From 2003 to 2006, they went up at an average of 43%/year. Then for the next 14 months, at 34%, the next three at 37, the next 3 at 60. But in general, the test is just done once year, so if you take out the early 2007 numbers, and assume we are working with all numbers in August, then, from 2003-2006 the avg was 60%, from 2006 - 2007, it was up 35%.

8/2003'...................... 8/23/2006.......................... 8/23/2007
0.89............................ 2.51.....................................3.38
......................................60%......... ..........................35%
So if you just look at it by year, the rate of increase is not changing upwards.

Anybody else want to take this on? I am really terrible at math, and can easily have made major errors in thinking and calculating here.

Anybody think the rate of change idea is wrong? I don't know where I read that or how long ago.

Which reminds me, why am I doing this rather than going to sleep? I dont' know nearly enough about the subject.

I just know the lizajane charts.

ok, g'night folks.
