So, once you're looking, how do you know what's normal and what's not? Know your ABCDs, that's how- it's an easy mnemonic to help you remember the red-flags that should send you straight to your friendly neighborhood dermatologist.
- A is for Asymmetry- Regular moles are uniform in shape- if you notice that one half of the mole is different than the other half, have it checked.
- B is for Border- Edges of healthy moles or nodules are smooth & well defined. Notched, uneven, or blurred edges may be cause for alarm.
- C is for Color- "Normal" moles are composed of one shade, where as unevenly colored moles that combine different shades of tan, brown and black should be examined.
- D is for Diameter- the size around the mole shouldn't be larger than 6 millimeters. If you don't have a metric ruler handy, that's about the size of a pencil eraser.
Now you know your ABCDs, go do a check and stay healthy! (Sing it right, folks!)
