Peace
This a scary time for you, and my heart goes out to you. It not going to be easy. I got myself all worked up before I went in as well, we all do, you will hear all kinds of stuff that will scare you, we all react different. Ask any Question you want to your doctor, and if you feel uncomfortable with it get another opinion, I felt good about my team, when I went into it.
I hope this helps alittle, I hope you the best.
