Hi Greg, you are in the right company here- we have all faced variants of the same dilemma. As you will have discovered already this is a situation in which getting hard data on which to base a decision is quite difficult- more that you would expect given how common PCa is. Nett nett, there is no single right or wrong choice.
The underlying problem is that there is both 'noise' and 'bias' in the information available to you: 'noise', in that different observers will legitimately interpret your situation differently ( interpreting scans is not the black and white thing we might like it to be- there's lots of greyscale of ambiguity) and 'bias' because there is a sense in which professionals will lean in the direction of their specialism when recommending a treatment plan. It's why MDTs are used to evaluate your case- to try to correct for these sources of error. ( And if we are being a bit more thorough, there is also latency, in that data on survival rates is, by definition, looking back to treatment standards which were current several years ago). Noise, bias and latency- don't be surprised that you are finding it difficult to make a decision. But you can and will find a way through.
It's not helpful here to suggest a preferred treatment for you- only you can evaluate the weight of the various probabilities of both treatment and the impact of side effect. But what I think one can say fairly safely is that if you are unsure, buy yourself some time to carry on reading and thinking. HT will slow things down and buy time which will take the pressure off and help you get to the point we all have to reach- making a decision that we can live with, whatever the eventual outcome. The most important thing, by far, is that you are at peace with your choice.
Keep reading, keep asking, keep thinking.
Best of luck
