D = diameter. Bigger moles are more worrying. That's the only warning sign I didn't have.
E = evolving. Rapid changes are a cause for concern and readers, this dodgy mole looked ABSOLUTELY NOTHING LIKE THAT a year ago. It was a neat little mid brown circle.

So anyway, see a doctor if your mole is fucked up in any of the ABCDE ways because apparently it takes forever for them to take the damn thing off.
