--and it's one thing after another. . .

Billye, I can't add much to what others have already said--I absolutely agree about the Vitamin D check (given your situation) and the preferences for the Mohs surgical technique in so sensitive an area, in order to save as much tissue as possible (and also given the drying effects of Sjogren's--make sure the plastic surgeon knows about this, and don't hesitate to educate him/her if you have to)--but, fortunately, this is one of the types of skin cancers that do not spread rapidly and readily, and you can likely expect a complete recovery.

Please let us know if there's anything else we can do (would you like me to lecture any of your body parts, perhaps? That would terrify anything . . . ).
