Have you ever had a cancer of any kind?

I had a small black spot removed from my nose a couple of weeks ago. While on an unrelated Dr’s visit I pointed it out. He just said, “Hm. Yeah. Just a mole. We can remove it if you want.”
A couple of days later I called and said, “Yeah. Let’s do it.”
Well, they sent it off to the lab. They just called. It came back as cancer. She didn’t sound at all concerned, just said they need to go a little deeper. Asked if I wanted to wait till January. I said, “No, I’d like to do it as soon as possible.”
Dr. wanted to let the area heal well first (don’t know why. Isn’t that kind of like making a sick inmate healthy before you execute him?) so they scheduled me for the 16th.

I’m freaking out a little here. Have any of you had any experiences like this?
