Could this be a skin cancer?

I've had this sore that hasn't healed on the outer portion of my right ear. The most recent symptoms are it sometimes develops a light crust but mostly it bleeds slightly at night. It used to crust a lot more but I've been trying not to touch it. It's mostly healed except for the night bleeding. Again, it's very light bleeding but enough to make me wonder. My ears have seen a lot of sun over the years as well, short hair or ponytails when it's longer. I have scheduled an appointment for a referral to a dermatologist but wondered if anyone else has had a similar experience in the meantime.
