I received my results today following an SCC biopsy.  Deep margin was 0.9mm and was given an option of having the procedure redone so a margin of 1mm is ensured or leaving it to see if another appears.  The doctor said she couldn't advise me and the decision had to be mine so at the time, I said I'd leave it and monitor it with a dermatology check-up booked for April.  However, I'm now having second thoughts and thinking it might be best to have it redone for peace of mind but I really don't know what to do for the best!
