Well, I had a multi-disciplinary team of up to twelve medics of various specialities review my case, and they told me to go for surgery, as I am suggesting to you.
You can spend too long studying Nomogram prognostications of recurrence fifteen years after surgery, as I suspect you have, by which time you might have died of something else!
Surgery should remove your cancer with what they call ‘curative intent’. The other treatments you are looking into complicate matters if you should need a subsequent prostatectomy, as the gland will no longer be clearly defined, and may have deteriorated into what a surgeon called ‘mush’, making a clean excision much more difficult. Very few surgeons will attempt such an operation anyway.
It’s your life, and your problem to resolve. I’m pleased you are here researching every option, but it’s your choice, and I hope it works out well for you.
