It's not another layer and no worries. i've thought of this too. The post surgery pathologist is the one that reported on the tubal. i tend to think he'd know the difference but it is something i need to ask along with all my other questions. i left it too late to know what the gyn was getting at after my surgery re: scarring...i can't find her now. i don't know what type of scarring is typical of endometriosis vs. abuse vs. the forced thing that happened to me at 12/13. All good questions. It goes on and on and on and on...
