It's certainly Nothing to mess around with.
My wife, a Florida girl, had a pimple on her upper lip, that wasn't normal, and wouldn't go away. Had Mohs surgery, lost 1/4 of her lip. Great reconstructive surgery, and she's fine now. That was 14 years ago. She also had breast cancer, last summer. She gets a mammogram again next month, so praying for that to be OK.
