Morning all - I had a very weird dream, - won't bore you with the details but it revolved around a wedding and someone saying to me 'your bottom isn't that special' , 
Telling people is a difficult thing to do, and you have to play it by ear a bit. Like topsy, I found it very hard to s the word 'cancer' - I kept bursting into tears, and I didn't want to do that because I didn't want people to know I was worried in case it made them more worried IYSWIM.
I think the age of your children is the main consideration in how you explain things, and how much you say. Mine were older, so I had to be pretty factual and detailed. I told them a few days before my mastectomy, the rest of my family, I told when I got home from hospital - so they weren't worrying about me having an op.
All my family coped much better than I imagined and were really supportive, - they want to help, they want to be able to 'do' something, so mine did loads of practical stuff. I had friends who got really upset when I told them, and have one who still finds it hard to talk about even now.
So I think its a question of picking your moment, and tailoring the info. and your tone, to who you are telling. But you need to consider yourself and when you feel ready. IME no one was offended that I kept it to myself while I was going through all the tests.
Camel - all the ups and down of feelings are exhausting in themselves - so take things as easy as you can, although you sound like a busy woman - hope the move goes smoothly, - is your little boy helping with the packing? 
amber - the skin over my mastectomy scar has gone very wrinkly and itches a lot since rads (even though it was nearly 3 years ago) I had it checked and it was pronounced normal. So get them to have a look - rads does affect and change your skin quite a lot, so I think it is very likely to be that.
Try not to panic 
Good luck with the herceptin tomorrow - keeping everything crossed that it is OK this time.
My mum phoned yesterday - she fell over, throwing bird food up onto the outhouse roof (for the seagulls ) fortunately escaped with only a graze. I have made her promise to let the seagulls fend for themselves and only put bird food on the ground and on the bird table I set up for her when I was there!
Definitely time for a
