Excellent news!
I had some PSA bounces of my own and also took about six years to reach
nadir, but didn't have anything as high as 7.5. My highest bounce was
1.8, but I have heard of a man with a PSA bounce up to 16.
One explanation I've heard for these bounces is that tumor cells produce
more PSA when under stress. Radiation can take a long time to kill
cells, even years. So when groups of cells finally begin to die, they
increase their PSA production.
Another explanation I've heard is that inflammation of the prostate
(prostatitis) can and does occur after radiation (due to the radiation)
and can continue to occur years later (due to some of the same reasons
that prostatitis occurs in healthy men.) Prostatitis of course does not
occur to men whose prostates were removed by surgery.
