Could this be removed? What does it look like?

I have had this for as long as I can remember, and I absolutely hate it. It is under/ on the side of MY BOOB. It looks like a mole to me, what does it look like to you? I've never talked to a doctor about it and thinking I should. Is there anyway I can remove this without talking to a doctor? Plus I get these hard black things that comes off of it if I pick at it.
