How To Tell The Difference Between A Normal Mole And A Malignant One

How can I tell the difference between a normal mole and a malignant one?

We have on our skin an average of 25 to 30 normal moles by the time we are probably 30 to 40 years old. What we're asking in order to determine abnormal moles is to look for those moles which are different than those 30. We do use a system to try to help patients to determine that. We call these the A, B, C, D and E of malignant melanoma. A stands for asymmetrical border. B stands for border irregularities, which is scalloping of the border. C stands for colour irregularity. D stands for diameter greater than 6 millimetres which is about the size of a pencil eraser. Finally E, which may be the most important, is evolving, or a changing lesion. So, with any pigmented lesion which is changing in any capacity; be it size, symptoms (for instance it itches or burns), colour, or elevation, we would like to know. Those are very important signs.
