The level of hazard for each mole is determined by :

1. The large number of them throughout the body.
2. A large diameter, a wart of over 6mm.
3. Morphological change of a mole (itching, pain, stinging).
4. If the color on the surface of a mole is not evenly distributed
5. Change in the size of an existing “mole” or the obvious enlargement of a new mole.
