You know how they say you should get any "suspicious" moles checked out by a doctor? Am I the only one who finds the term "suspicious" a little vague and, well, suspicious? How the heck am I supposed to know what moles are safe and which are just cancer waiting to happen?

Luckily, there's this quiz that helps explain the difference between a normal ol' mole and one that should send you running to the dermatologist. It's so easy -- and a lot quicker than a stint in a doctor's waiting room (there are only so many back issues of Self magazine a person can read, am I right?).

Just take a glance at your moles and answer a few questions. It'll put your mind at ease, or let you know if there's a derm visit in your near future. Here's a sample:
