Hello LIZS
- I posted on carpejugulums thread, - I managed in my usual idiot way to misread your post and thought it was you who had BC, - I'm very glad it isn't, but very sorry to hear about your relative, and of course you are very welcome on this thread.
I had a mastectomy rather than a lumpectomy, and for that the recovery time was about 3 weeks of feeling fairly sore at the wound site, and with lymph node removal there can sometimes be a bit of nerve damage, - they rummage around a lot. So it's really important to religiously do the exercises they give you in hospital - they really help a lot.
How much they remove will I think depend on what the margins are, - they will want to get a clear margin of non cancerous tissue, so that may all be a bit of an unknown factor until they actually operate.
My aunty had a lumpectomy and RT last year - she was 88 at the time, and is still going strong and making good progress, - she also had lymph node involvement. She told me the thing she found hardest was the tiredness, especially from the RT, and she struggled a bit - her sons both stayed with her for a while to help out. - Does your relative have anyone nearby to help with household chores, cooking etc? Also it is nice to have someone to go with you to RT - as often there is a bit of waiting around, and the whole hospital business can be a bit overwhelming.
Very best of luck to her 
Lone - you have made your decision by the sound of it, and I would have ,made exactly the same choice in your position, - good luck with the op. xx
I4K - so sorry to see you back ( I mean it's lovely to see you but, wish you weren't here IYSWIM), - I'm sorry you have all this anxiety again, what an absolute bugger 
Asho - If I'd had the offer of a picc line I'd have taken it, and if it happened again, I'd insist on one, - my veins were shot to hell and really painful (mind you I am old!!) but chemo is such a battering to your poor old arm, - and I had problems when I needed IV antibiotics while on chemo - my veins kept breaking from the damage, and they couldn't tell how much had got into me. definitely worth considering if you are offered it IMO.
SR - hope all the family are well, and DS is getting on with e njoying uni life after the GF problems.
Smee- love the sound of DS's costume - you are brave to trust him with your G and B's 
Waving hello MAS, Jane, Gig and everyone else I've missed, hope all are well. I have a cold - the kind that means you have a constant river of snot coming out of your nose - delightful!
