|FotoFinder Dermoscope Test
|To assist the doctor in mole mapping for the early detection of malignant and benign melanoma||Using an instrument called a FotoFinder dermoscope, each mole is compared with an overview image of the prior examination.||Normal moles will not change over time.|
|To determine whether a suspicious area contains cancerous cells||A small sample of skin is removed for laboratory analysis through one of the five following methods:

Excisional – the whole abnormal area is removed by surgical knife.
