Moles are lesions that are largely benign. In a small percentage, however, they can develop into more aggressive lesions and, very rarely, into the worst skin cancer: malignant melanoma.

For the diagnosis of melanoma and melanchromatic skin lesions, special methods are used, such as dermoscopy and computer mapping.

The initial screening of nevi is done by careful clinical examination combined with dermoscopy. The latter is a special clinical method in which a dermoscope is used, i.e. a special high-resolution and high-definition lens that allows dermatologists to see "inside" the lesion. In this way, in the first instance, moles are assessed and conclusions are drawn as to whether a mole should be surgically removed.

Some people with many nevi need to have digital nevus mapping. Digital nevus mapping uses very high resolution lenses to capture even the most subtle features of nevi. This method allows digital photography of areas of the body in order to be able to record and assess any new nevi that may appear, and also allows each nevus to be recorded individually.

The whole procedure takes no more than an hour and is repeated more often every year or sooner if necessary.

For patients belonging to high-risk groups for skin cancer, periodic monitoring of the size and microscopic structure of the nevi is recommended.
