Sorry to invite you to club.
Your 3+4=7 is a good number if you have to have PC. That is what mine was.

Right now to early for you to try to decide on what to do. Wait until you get the results of the Decipher and PSMA test you mentioned you are going to get. Those test are really going to help determine the risk and stage of your PC.

I was not young when I had proton radiation. I was 76. However was very active with swimming, walking, and water aerobics. I had been doing Sprint Triathons but had to stop bike riding so those races stopped also. I had minor fatique about half way in through my 30 doses of proton radiation. I did not have hormone treatments and that is where your Decipher test will really help like mine did.

There are many different radiation treatments out there to consider. The newer ones can offer a 5 day course versus 20-30 doses over months versus 1.5 weeks. The time it takes to do a radiation treatment is minimal total time there probably less than 30 minutes with only about 10 minutes on table. Just giving you what is norm at UFHPTI and what I had.

Wait for those Decipher and PSMA test as will determine if need hormone treatments which make a huge difference in how you will feel. With radiation there is no symptoms having the treatments just over time you can have side affects that most likely would not prevent you from working.
