My own surgeon, in a pre-surgery conference, warned me that I needed to start doing physical therapy NOW to strengthen my bladder muscles so I could rapidly regain continence after the operation..He said "should you need follow-up radiation treatment, the radiation will "freeze" my continence level right where it is and there will be no improvement after radiation is started..
I translated that to mean that the radiation will damage already damaged tissue and the healing process stops right there.. Purgatories experience would seem to support this.
What the research says:
Published research series have already demonstrated advantages of
IMRT over 3-D conformal radiation at higher dose levels. Meanwhile,
several recent studies have even demonstrated the lack of superiority of
protons over 3D conformal radiation. We are unaware of any proton
study series utilizing higher doses than 3D conformal radiation. The
preponderance of data suggests that higher doses equal higher cure
rates. It is not possible to safely escalate protons to doses as high as
those used with 4D IG-IMRT coupled with a Palladium-103
brachytherapy. It has been well documented that it requires far higher
doses of radiation to truly eradicate prostate cancer. This is
accomplished only with 4D IG-IMRT utilizing DART and Pd-103
brachytherapy, which also has the advantage of maximally sparing
adjacent normal tissues -- neither is achieved with protons.

PSA at age 68, 7.0, third biopsy positive for cancer in 4 cores, 3 cores Gleason 6, one core Gleason 9. Finesteride discontinued, still no urinary symptoms, never had any..From age 55 to 65 I had no health insurance.
I have a date with the robo surgeon on Sept 3 but I'm keeping my options
open. A "top" radiation oncologist here in Denver, equipped with the latest IMRT/IGRT/RapidArc machine says he can do better by me..
