The estimate comes from a linear model ==> 3.5/16 months = 0.21875/month
* 4 months (May - Aug) = 0.875
==> Aug PSA ~ 6.2
 
Diagnosis: T1c, Gleason 3+3, no symptoms, no cancer found by DRE, TRUS; only in 2 of 14 biopsy cores; some cancer found in 1 Sep 1999 MRI Spectroscopy
 
Graphical Image of PSA vs Time
 
Note that PSA reliability/reproducibility/variability is about +/- 10-15%
 
See the discussion in the full document ( http://www.cohensw.com/mvpcsg_nov99_text.html)
The anomolous values of May 2001, Jan 2002 and the Winter of 2005 are due to bouts of prostatitis.
The gradual rise since 2006 has ben due to BPH.
It is not clear to me why my PSA has been declining since Feb 2020.
Unless otherwise noted, all PSA measurements were done at Stanford Hospital
Free PSA < 10% is indicative of cancer, >20% no cancer (for PSA < 10)
