How deep they go depends on the lesion. There may be some stitches, depending on how big and deep they have to go. The one I had was on my hand, and I went to a plastic surgeon to have it removed, since hands show scars. He did a great job, because I can't even see where it was removed!
They will send whatever they take off to be biopsied and make sure that the borders are clean (no cancer cells). If there are cancer cells on the borders, they'll have to go back and take more until they get clean borders.
My doctor has told me that he might have to go back for more after the biopsy, but I've never had to actually do that. Don't worry...you'll do fine. Let us know how it goes!
