Examples of Skin Lesions

Figure 1: Benign Nevi.	Figure 2: Dysplastic Nevi.	Figure 3: Malignant Melanoma.

Figure 1 shows a healthy skin lesion. This lesion has no particular risk of developing cancer. In figure 2 a dysplatic nevi is shown. This is a skin lesion, that has a higher risk of developing cancer and is therefore often said to be a precursor to cancer. Figure 3 shows a melanoma. This lesion has cancer.
