[Skin cancer from solar ultraviolet radiation exposure at work].

Due to their professional activities, outdoor workers are exposed to an increased risk of developing occupational skin cancer caused by solar ultraviolet (UV) radiation as defined by occupational disease (OD) number 5103. Since the amendment to the Occupational Diseases Ordinance ("Berufskrankheitenverordnung", BKV) in 2015, squamous cell carcinomas or multiple actinic keratoses of the skin caused by natural UV radiation in outdoor workers in Germany can be recognized as occupational disease in the sense of OD number 5103. The main cause of nonmelanoma skin cancer (NMSC) is solar UV radiation; it is the most relevant occupational carcinogen in terms of the number of exposed workers (i.e., outdoor workers). Circumstances associated with climate change include increased terrestrial UV radiation, an increase in the number of cloudless days and therefore the number of hours of direct sunshine, adverse meteorological effects to the stratospheric ozone layer, and so-called low ozone events and associated more intense UV radiation. In the future, comprehensive considerations will have to be made as to how prevention concepts can be effectively designed to avoid the development of occupational skin cancer in outdoor workers. The treatment of future cases of skin cancer will be a particular challenge due to their high number and only a limited number of dermatologists available. Hopefully, prevention of skin cancer will become even more important in the future.
