If he did the ED&C to "get a better look" at the lesion below the surface, and if the lesion is bigger now because he can see it better the use the largest measurement after the ED&C if is is smaller then use the largest measurement prior to. The end result is take the largest measurement.Still a little confused. On the same site/ the doctor indicates the lesion size and the lesion size after ED&C. Then he excises the same lesion. From which size would you add the margins to get the diameter?
