Your Guide to Early Detection

Quick downloadable tips for early detection (download the guide)

Know your skin: It is important to note any changes to your skin. Use the following as a general guide when performing monthly self-skin exams.

A: Asymmetry. If you were to divide the mole in half vertically, would it be the same on both sides? What if you divide it in half horizontally, or diagonally? You want your moles to be the same no matter which way you divide it in half.

B: Border. What does the border of your mole look like? Is it smooth? Is it irregular, blurred or poorly defined? The border of your moles should be smooth, well defined, and even.

C: Color. Moles can come in a variety of different colors black, white, red, brown, and even blue. What you’re looking for here is that your mole is the same color throughout. You want to make sure your mole does not have different shades of the same color or completely different colors from one area to the next.

D: Diameter. How big is your mole? Melanoma can be in any sized mole, but most healthy moles do not exceed the size of a pencil eraser, about ¼ of an inch, 6 millimeters. If your mole if bigger it should be examined by a dermatologist.

E: Evolving. Has your mole been changing over time? The best tip here is to take a picture of it every month so you can compare each time you do a self-exam. You are looking for any difference here—color, shape, or size.

If you find a mole that does not pass one or more of the ABCDEs of melanoma, see a dermatologist. Also see a dermatologist if you have a mole that itches or bleeds or if you find a nodule under your skin. It is better to get a mole you are unsure about checked just to be safe.
