What are the malignant melanoma warning signs?
Malignant melanoma, which is an atypical mole that is having both abnormal growth and biological behaviour, has to be distinguished from normal moles. There are approximately twenty-five to thirty normal moles per person, so that is asking someone to be able to tell the difference between something that belongs there from something that is slightly different than something that belongs there. We use a pneumonic; A, B, C, D and E to look for some of those moles which are of greater concern. A stands for asymmetrical, which means that the mole is different on one side than it is the other. B means border irregularity, which means that the borders are not sharply demarcated. C is colour irregularity, which means the colour is not one uniform colour throughout. D is a diameter greater than a pencil eraser (six millimetres). E means evolving, or a lesion that's changing. I tell my patients that if it looks like a mole was put on by a draughtsman, it's probably ok.
