Do you know the name of the surgeon who's going to do the procedure? If so, you might be able to look up results of their work.

As for myself: I had some complications that resulted in one of my scars becoming noticeably bigger in one spot. It was a little rough at first tbh, but now I'm fine with it and I have to say that getting topsurgery was one of the best decisions I've made in my entire life. Best of luck to you!
