A long response that answers all your questions —>

I’m AA; I was 65y/o when I was diagnosed with localized, 3+4=7, PSA = 7.976.
I spent many months evaluating all treatment options. My urologist (a surgeon) provided me referrals for focal therapy (cryo, HIFU, ablation), brachytherapy (LDR/HDR), SBRT (Cyberknife; Trubeam), IMRT & Proton.

With success rates comparing surgery with radiation being statistically equivalent no matter what treatment chosen (https://www.nejm.org/doi/full/10.1056/NEJMoa2214122), it all came down to side-effects and quality-of-life (or as that paper concludes, “… the choice of therapy involves weighing trade-offs between benefits and harms associated with treatments for localized prostate cancer.”).

For me, I wanted to balance survival (of course!) with quality-of-life, along with the possibility of treatment in the future if needed (as medical treatments progress). I wanted the least chance of ED, GU, GI, bowel or other similar complications - quality-of-life following treatment was a priority.

After spending much time getting referrals and evaluating treatment options, I ranked them as:
#1. Proton
#2. IMRT
#3. SBRT
#4. surgery

I had 28 sessions of proton radiation during April-May 2021. Treatments were relatively uneventful. I only had 1 day of adverse side-effects. (My wife later told me that if she hadn’t known I was undergoing radiation treatments, she wouldn’t have realized it from any change in me.)

The idea that “if you choose radiation first, you cannot have surgery later” has some truth to it, but is old-school and doesn’t consider modern treatment techniques. With radiation, the DNA in healthy prostate cells get damaged just as do the ones in cancerous prostate cells. But healthy prostate cells have repair mechanisms that can sometimes repair the damage (though not always). Cancerous prostate cancer cells usually can’t repair the DNA damage. What’s left is a “healthy” prostate, 35%-50% smaller than it was, but damaged enough that it makes salvage prostatectomy challenging (though not impossible).

However, if there is local recurrence after initial radiation, choice of treatment would depend on the nature of the recurrence; there are other options (other than surgery) - focal therapy (e.g., cryo), brachytherapy, SBRT, and yes even re-radiation in some cases. Surgery would still be the distant last choice. So, I wouldn’t let the old-school “no options if recurrence after radiation” philosophy change my initial treatment decision.

About PSA testing —> With the current state of medicine, PSA testing (or PSE testing) is the only (& least expensive) test there is for early-detection of prostate cancer. However….. Remember that a PSA test is not a cancer test. The PSA number itself is similar to a “check engine” light in a car; it indicates that something may be wrong, and further checks should be made “under the hood.” Might be as simple as a UTI; might be BPH; might be more serious, such as cancer. Just need to have further checks. No need to panic, or rush to a quick treatment decision, or get overly concerned.

Yes, it is possible that someone could have the “seeds” of prostate cancer for some time, but too small to be detected. In my case, I was on active surveillance for 9 years (having been initially diagnosed in 2012 at 56y), before the prostate cancer which was initially low-grade became intermediate grade.

Note that there are only 47 active proton centers in the U.S. (The one at the University of Cincinnati was just a 40-minute drive for me.). Is there a proton center near you? —> https://www.proton-therapy.org/map/
