It's great that you got an appointment with a dermatologist so quickly. It can take months in some parts of the US to get a dermatologist appointment.

Ears tend to bleed a lot if they get even the tiniest cut, so that part sounds normal.

There are lots of things that can cause a small spot on your skin. I've had a couple of precancerous spots that the dermatologist removed with liquid nitrogen. It stung but wasn't really very painful.

I'm very fair like you are and had lots of sun exposure during my childhood. I was going to ignore the first spot I got, except it was on the END OF MY NOSE so I went to get it checked out because it was impossible to ignore.
