Many thanks for your reply Loose Rivets.
Dad was told at diagnosis that even if nothing was done, it wouldn’t be an issue for 5 - 8 years which seems strange seeing it was already ‘locally advanced’
Yes, it was temporary brachytherapy and at the time, the specialist was pretty confident that it had all been zapped but recommended the Zoladex for 2 years as belt and braces. Although dad says the nocturnal visits are much reduced, he still gets up a couple of times some nights so I think he’s concerned that there might still be a problem. I’ve read online that Brachytherapy in itself can cause some long term urinary issues which I hoped should reassure him.
Interesting to know also that at 71, the growth, if it’s still there, will be slower. I had no idea so many thanks.
