[Non-melanoma skin cancer : Pathogenesis, prevalence and prevention].

Non-melanoma skin cancer (NMSC) is the most common malignancy of the light-skinned population with an enormous socioeconomic impact. Historically known as incurable under the term noli me tangere (transl. do not touch me), today various non-melanocytic cutaneous neoplasms are grouped as NMSC. The most common of these, basal cell carcinoma, squamous cell carcinoma and actinic keratoses as carcinomas in situ, are increasingly called keratinocyte carcinoma. Today, the pathogenesis and risk factors of NMSC are relatively well understood, which has led to multiple treatment options, the recognition of NMSC as an occupational disease in Germany and a variety of prevention approaches. Although there is largely general consensus in the dermatological world, knowledge of affected high-risk groups in NMSC and prevention is still very low. The development of target group-oriented awareness and prevention campaigns are therefore urgently needed.
