Well done on getting thru all the yucky stuff, as @kezmusc has put it! ;) No need to make a rushed decision .... you will already have an idea of what you will like as an outcome ... go with what feels right for you. This may or may not involve further surgery.
I was lucky, @Emim - I'd never realised that my 'BC breast' was somewhat bigger than my 'OK breast'! So, by the time the tumour had been removed by lumpectomy, both breasts were basically the same size, just the BC breast being 'flatter' across the nipple area, where the tumour was based, and have a divot right on the edge of the nipple - but not keen on more surgery unless it is absolutely necessary for my health. I am not worried about this - but will point it out to the surgeon when I see him in a couple of weeks for my 1 year review.
I find it really 'weird' that I had never noticed the different breast sizes over 65 years of looking at myself in the mirror!! LOL The surgeon picked up on it in the first 5 mins on my first meeting with him in Jan last year!!
All the best with your decision making xxx
