Hi Sheelagh,
I had 2 types of radio. The first week focussed on my whole boob and that is what I think everyone normally has.
As I had v small margins on one side of my lump (0.3mm) I then had a 2nd week with a different dose targetted on that specific area.
Separately, sock news. It was a normal sock, black, clean (!), rolled into a ball. Quite comfy actually and not at all noticeable as I’m an A/B cup, so at least I wasn’t concave 
The conference was a bit knackering, 4.5 hrs there, 3 miles walking and 3.5 hrs travelling back. I was, again, back in time to be tucked up with Mr Hollywood then conked out for 9 hours! No cake dreams to report
