Which Mayo are you at? I got my MRI and biopsies at Mayo Jacksonville. Surgery was only propose as an option along with choosing radiation. Where you not offered both treatments?

Everyone is different and will respond different to radiation treatments. Some will have noted side affects and some very little or none. I had minor side affects that went slowly away. None of them changed my lifestyle in any way.
You mentioned surgery. The surgery is major not minor and does have a lot of side affects but again some do very well and some do not after surgery. This is normal with any surgeries.

My suggestion: Have your R/O offered the following tests? Decipher, PSMA, bone scans. They determine if your cancer is agressive (Decipher) and gives a risk level. PSMA shows if cancer has spread beyond prostrate. Bone Scans show if in bones.

If all those come back negative and low or even itermediate risks radiation is a very good option. This comes from Mayo R/O, UFHPTI R/O and my Mayo PCP. Not my personal opinon. But this was for me.

I had the same test results you had. 3+4=7 and 2. I was told surgery was option and gave me all the pros and cons. Radiation with hormone treatments pros and cons. Radiation only pros and cons. Then I had all the above test done and what the R/Os recommended was radiation NO hormome treatments.

My 3.75 at time of treatments is now .44 a year after treatments ended and I HAVE NO side affects remaining. I reached below 1 on my first 3 month after treatments that was goal of R/O. Now I have my PSA check every 3 months.

I wish you luck but really do some research get second opinions. Get the other test that will help guide you and your R/O or urologist recommend the best treatment for you.
