Surgery

I found out a couple days ago that I have to have my first ever surgery.  I have a cystic mass on my right ovary and it has to come out.  My first surgery at 49 1/2 years old.  I am a bit scared about the whole thing.  Do I have both ovaries taken out??? That's the other question to ponder.  I will let you know when it's scheduled.  Thanks for praying for me.
