Well done on making a choice:) Each small step forward is a step towards the finish line!! I had a single mastectomy,and the first time I had a mammogram and ultrasound after my surgery,they did an ultrasound of the mastectomy side.But since then,they haven't done it.When I see my surgeon and oncologist( 6 monthly) they always check the scar line,and I check it too.Apparently that is all that is needed.In the beginning I thought that it wasn't enough,but now I realise that it is fine.As for your surgery,put things that you use on a daily basis,at bench height,so as you don't have to stretch in the first few days,and the other most important thing that I would say is to do the exercises that you get given,even if it is difficult in the beginning.All the best and stay in touch on here.Cheers Robyn xox
