Was there any mention of excision on your discharge forms?. I found with my latest 2 visits there was a brief description of the work they carried out. If your eager to find out before your next visit you will probably find the team has a secretary and if you speak to them they will be able to give you details of what went on
Both times with me they have excised, and I only has to revisit when part of mine grew back (how much I dont know as one side always had heavy scar tissue). I think ive been lucky with the NHS so far, both of my local GP`s I have dealt with and the surgeons ive had have been very knowledgeable in this subject.
