Hello MrsS - I feel horribly guilty that I didn't keep up with your last thread and therefore missed this one until now! I've been an MN lightweight though for the last few weeks. 
I hope the remission is complete - and long-lasting! I can understand your bewilderment - this has been your focus for months and now it's taken off the boil, as it were, while still not being completely over. You'll find a new "normal" again pretty soon though, I think.
Echo - your DH's PSA (prostate specific antigen) levels are an indicator of problems, as you have realised; the hormone levels will be a different substance (although I can't remember which hormone they test for). My Dad had Ca prostate a few years ago, and he had an 8 point needly biopsy of his prostate, of which 2 came back positive, one was dodgy and the rest were clear. Because of this, he only had radiotherapy for his treatment and it was successful. He still goes up to the Royal Marsden every 6m for a check up, and has his PSA checked every month to ensure it stays under 4. So far, so good! Up to you entirely but you might want to have a look at this lady's book Prof Jane Plant - she herself had breast cancer 5 times and then managed to get rid of it after some interesting realisations. She's no quack - she was the geologist to the Crown at one point.
Anyway - it can't hurt and it could help. She has also written another one, more personal to her, about breast cancer.
Please note: at no point should these suggestions I make be taken to be "instead of" conventional treatment - only ever as an adjunct, and only if you want to.
Similarly I'd like to link again to the Penny Brohn Cancer Care unit in Bristol - there for advice on diet, lifestyle, counselling services etc. but all to go alongside conventional cancer treatment.
I hope Daisy is ok - and that her DH is actually resting from work a bit now! :( for her.
I'm only here to hold hands and offer the occasional bit of hopefully useful advice, my parents, niece and other family members have had cancer, with varying outcomes, so I have some idea of what it's like but not in any way like you are going through just now.
