Sorry to read that. With a PSA of 3.5 I'd have been thinking it's unlikely to be significant.
With this illness little is certain so thinking in terms of probability can be helpful.
I was flat out and fully blinkered to get the op and I still think it right. Although I now know there are times when RT is very probably better. Such as when it might be locally outside the prostate.
Mine was upgraded when they got it in the lab. That's an advantage with the op. They examine the prostate and can also say if it's got negative margins, which is good. Knowing this information gives you a bit more re-assurance as long as it's good news.
With RT, hormones may start right away which makes it seem like treatment is happening but the lesion is still there. You may not need a fast operation but if it's going to happen better get it done in my opinion especially with the delays they speak of.
There's a lot to take in.
All the best, Peter
