@jgrummerf Welcome to Mayo Clinic Connect. Hearing skin cancer can certainly pull us up short, can't it? I have dealt with basal cell of different types, squamous of different types, and melanoma. And, I have the surgery scars to prove it! Earned every one of them.

The invasive squamous from last year was on the back of my right arm, and required a 6-stitch MOHS surgery. Earlier that year was basal in my left eyebrow, and now I have a spot just biopsied on left nostril that most likely come back as invasive squamous. As @windyshores mentioned, "well defined" is good! The anodular basal cell on my collarbone had spread under my skin, and needed an awesome lightning-strike looking MOHS scar to clear, and the amelanotic melanoma on right forearm needed a 32 stitch horseshoe shaped incision to excise. There are others, too, but these are the most impressive LOL

I hope you will let us know what your doctor tells you on the 17th, so we may support you.
