As per above, it is 1 cm. I am an RN for Rad/Onc docs, and of course, they say RDT will be better cosmesis, and 95% curative. I have seen a MOHs board certified doc, who says 99% curative, but the scarring could be substantial. Scheduled to see a plastics guy this week. I am really struggling to make this decision. I am 57 y/o, active and in good health. Any thoughts?
