I've had Mohs twice, both times from a specialist dermatologist surgeon in Houston who did hundreds of them every year. It was inconvenient to drive an hour and a half but the technique is very efficient as DnvrFox describes. They trim the least amount of flesh surrounding the area, freeze it, slice it very thin & examine each slice carefully for cancer cells. This manner allows them to see x-sections of the affect spot & if they have to do a 2nd slice, they only take it where the cells show up in the x-section. My nose has had 2 & initially the scars were about as deep & wide as a quarter. Over time they've filled in and shrunk almost to invisibility. I think it's worth the trouble to find a Mohs specialist, at least from my experience.
