Hey Blast,
Welcome to the skin cancer club. Us white boys that grew up in TX often have a problem with that. Fortunately, mine was just a basal cell carcinoma, which isn't terribly aggressive.
I got a cool scar on my back to show for it, and an annual appointment with my dermatologist for the rest of my life.
Hope your surgery goes well, and it doesn't keep you off your feet too long.
Greg
