Re: Scared of having polops removed
First, most polyps are benign.
As for your other questions . . . it depends on your specific situation. So only your doctor can answer them. If you are completely preoccupied, you might try calling the doctor's office and ask the basic questions. "Will it be a one day procedure or do I need to be preparing for a hospital stay of a couple of days?" I should think that much one of the nurses could find out for you.
The first time we face possible medical procedures, it is scary. (I was "lucky"; for my first operation, I went straight from the ER to the OR, so I didn't have time to think about it!) Just remember that the overwhelming majority go like clockwork.
