Hi, Have you any knowledge of the size of the lesion or exactly where it's located.
It might be academic to some degree but one of the things that comforted me in my choice was it was close to the outer edge at the apex, and 13mm diameter or at least said to be 13mm.
Close to the edge put some urgency on it and the size seemed fairly large for radiation. Although they say they shrink it with hormones before radiation my simple mind didn't like the idea it was close to the edge and 13mm seemed pretty large for one side of the prostate. For those reasons I was keen to get surgery done.
At the time I was Gleason 4+3 but in the lab after the op they said it was 4+4 which put it in high risk. So I was glad it was out. I was told the good news is negative margins. None of that information is available to radiation patients but most people don't regret their choice. It will also be a year before you know if it worked whereas you know within 6 weeks if the op worked and from then you're hoping it doesn't come back.
Brachytherapy wasn't offered to me and they gave me strange looks when I mentioned it. Not done here I think. I've never felt regrets anyway. So all the best. Peter
