Hello Splodge,
I got a similar diagnosis to you at the beginning of 2024, T3b N0 M0 3+4, very early seminal vesical involvement. I was offered the choice of surgery or radiotherapy with hormone therapy. One surgeon recommended surgery, then a second I saw after the first was unavailable after a family emergency said RT! I opted for RT in the end after agonising over the choice lots. Mainly because the second surgeon said he could do surgery, but it wouldn't be nerve sparing and I'd most likely need salvage RT.
I'm happy with my choice so far, completed RT and a session of HDR brachytherapy at the end of 2024.
Just another 18 months to go on hormone therapy! I've faired ok on that luckily, though others have suffered more with the side effects.
I'd say don't rush any decision once all your results are back, prostate cancer is generally slow in progressing. Speak to both surgeons and radiologists. You should also get a recommended route from your MDT. The specialist nurses on the above number are great too.
All the best with what ever route you choose, you're right all the waiting is the worst! I felt much better once I'd made my choice and a plan was in place.
