@FLClover thanks for checking in. Everything went well and I spent many hours sleeping the anaesthetic off. I feel very comfortable - morphine PCA is great stuff.
The surgeon dropped by and told ‘me good call’ to take the breast off. He thinks pathology will show some nasties - he said it was very lumpy although nothing too obvious. That’s scary but I spent the last couple of days feeling like I was putting my family through yet another experience they didn’t need - my eldest daughter is a week off beginning her year 12 exams and is struggling with the pressure - so I feel happier that I went ahead with it.
