The disclosure regarding the Prostate Specific Antigen is nothing new.
My uro kept reminding me, countless times, that the PSA is a 'marker'
only: an indicator and that measures are being made to develop a more
reliable test.  Even the DRE only searches the back side of the
prostate and doesn't come close to discovering the front or sides of
either nodule.  Unfortunately nothing else more reliable has come up.
I think you're right on the change of the threshhold and examining
other factors.  Now that I think about it even the biopsy can miss.
My PCa was at the apex of the gland and was almost missed had the
doctor stayed in 'the-center-of-mass'. The sonogram he was being
guided by showed the cancer density yet the field was difficult to
determine.  I also think they need to stress testing for this disease
at an earlier age than the current forty five.  Family history needs
to be factored in and really stressed publicly.  My two sons are both
in their early twenties and are aware of their chances.  Then again we
need a more absolute preventitive and not just 'wives tales', promises
from vitamin companies and trendy media-hyped fad diets proclaiming
they'll prevent cancers.  Okay.  I am climbing off my soap box now.
Even though it seems, with all the technological advances we've made,
that cancer research is lagging consider where they were only twenty
years ago.  My mother-in-law dies from glioblastoma which was a death
sentence in the '80's.  Now at least there are survivable odds.  I may
not get to see it but they're getting closer all the time to
discovering what trips of cancer cells.
