There are plenty of sources online to tell you what to look for, but my dermatologist sticks with "pink and brown makes you frown". Irregularly shaped with strange combination of pink and brown is a flag to watch out for.

I've had a couple basal cells (the way less scary one) and the easiest way to identify those is just look for a pearly pimple that won't go away.
