Your POV is very much a common response and IMHO, a potentially deadly one.
“OMG, get it out” is so common and there is a large body of surgeons, and although I would not say they say: “cut it out,” malevolently, there is that $ factor and after all “if you’re a hammer,” then “bring on the nails,” you don’t want anyone considering alternatives like staples, or glue.
There is a support group that I attend, “Reluctant Brotherhood,” composed of many, in many stages of prostate cancer and the one take-away I’ve found is: Do NOT rush into a decision. And there are many there, who have lost erectile function, who are bladder and fecal incontinent.
I would never criticize any, for it is axiomatic that we always do what we this is the best for us. But I see surgery receding more and more into history.
Spring of 2022 FDC allowed PSMA-PET scans. I’ll have one tomorrow. IV injection of a radioactive gallium that has a rather insane attraction for the cell envelope of prostate cancer cells, we’re talking 1000x the uptake of normal cancer cells. They wait an hour, then do a PET scan. If there’s a 1/8" tumor in the tip of your nose, the image will show a white hotspot. It catches about 80% of all prostate cancers that have moved outside the prostate (and may miss 1:5 as they might be too small (microscopic).
So four years ago it was: You have cancer, cut the prostate out, but 'ya, know maybe we did not get it all so let’s radiate the bajeebubs out of you and then chemically castrate you for a year or three with hormone therapy.
Doc said to me: “Why are you negative on hormone therapy?” My response: Because it will turn me into a feeble-minded, feeble-bodied, no longer a guy, with big boobs, hot-flashes and mood-swings and if a 23-year old cheerleader were to jump in bed with me, I’d say, go away, I’m hot."
Ok, perhaps I’m too heavy handed there, for there are times where surgery, and/or hormone therapy (chemical castration) are necessary–or you die.
Here is the issue: Doc’s view: “I must cure him by destroying the cancer.” The doc does not care what the adverse effects are. Doc has one goal: Cure you, it matters not if, near the end, you’d much rather be dead.
Nowadays, PSMA-Pet has changed the prostate cancer world. With an 80% accuracy we can now say: “It’s not spread, so we don’t need to do hormone therapy.” This was not the case several years ago–huge change.
Also are things like (new this year) MIRdian-Linac. This is a linear accelerator that is so precise that if the patient takes a breath-out-of-sync, it detects the movement of the prostate and stops the beam and waits till the breath ends. The Miridian system has also dropped many radiation treatments from 6-8 weeks, 5x/week, to one or two weeks, with remarkably less adverse effects as urinary or fecal incontinence. Wow!
A wise CaP victim is best advised to “trust everyone–but cut the cards” ( = trust no-one). Get 2nd and if necessary 3rd opinions, ask a lot of questions. And drop your doc like a hot potato if you detect something wrong. It’s no longer a “doc world,” it has moved now closer to where the patient can be a real partner.
I’ll get off my soap-box now.
