In addition, youll learn about next-phase treatments such as immunotherapy or targeted chemotherapy drugs for later-stage disease. In contrast, a policy of biopsying every atypical mole would require nearly 2,000 biopsies per melanoma diagnosed, while failing to diagnose the 85% of melanomas that did not arise from an atypical mole and leading to an untenable cost-benefit ratio.13,14,28.

Dysplastic nevi are linked to a combination of environmental elements and genetics, but researchers are still studying exactly what causes them. The skin on the surface may break down and look scraped. The increased risk might be because of a shared family lifestyle of frequent sun exposure, a family tendency to have fair skin, certain gene changes (mutations) that run in a family, or a combination of these factors. It is an acquired mole demonstrating a unique clinical and histopathologic appearance that sets it apart from the common nevus. Different cancers have different risk factors.
