Thanks, everyone, for your replies. I wanted to update you, in case anyone was wondering how it turned out.
The very next morning after I discovered this spot, I dropped in on my general surgeon without an appointment. He had removed moles for me in the past. He agreed to see me, and removed the mole that same morning. It came back benign, although he said it was a type that could develop into cancer down the road.
So I'm thankful he was so accommodating!!
