It is normal, my surgeon did it himself and discussed what he was doing. I think he knew just enough about me then (we know each other much better now!) to know that I welcomed knowing what was going on. He also advised that he was going to remove a small spot just above my breast as he thought it might be a skin cancer - it wasn't (benign neurofibroma) but I remember thinking that was pretty thorough! I went to surgery very soon after diagnosis so there wasn't a lot of time for anything but attitude counts for a lot. How someone does something can impact as much as what they do. Bottom line, you don't need to carry this distressing memory - it's worth talking to a professional about how you can best let it go. Best wishes.
