DCIS... what are optimal clear margins

Ive had central WLE /SnB for idc… histology showed large area of undetected dcis (intermediate). I’m having re excision to improve my dcis margins but what is the optimal size of margin for this?

Hi feenix. I think they like a 5mm clear margin. I had a cavity shave as clear margins were only achieved on 2 sides. One of my margins was only 0.5 of a millimetre clear as it was to the skin so they couldnt achieve any more. Good luck with yours and i hope you get clear margins xx
