Results of a 10-year web-based health promotion campaign against skin cancer in Switzerland.

Abstract

Skin cancer is the most common malignancy with rising incidence. Although early detection can be lifesaving, prevention programmes are under-utilized. In 2008, a group of board-certified dermatologists in Switzerland established a website aimed at educating about skin cancer risk factors and providing guidance on self-assessment. To present the data of this programme over the last 10 years with regards to representation of the targeted groups and sustained impact on primary skin cancer prevention. A comprehensive web-based health promotion campaign was established for education and guidance on self-assessment. Teledermatological evaluation was offered and participants were then interviewed. In total, 11,171 digital photos were evaluated during 2008-2018; 54.3% (n = 6,067) from females and 45.7% (n = 5,104) from males. In 26.7% (n = 2,983), clinical examination was recommended. Of the participants, 1,874 replied revealing 103 malignancies (9.2% of the lesions were presented to a physician): 34 melanomas in situ, six squamous cell carcinomas, 53 basal cell carcinomas and 10 malignant lesions (not further specified). Of the participants, 40.5% (n = 683) changed their attitude towards sun exposure, 48.7% (n = 820) used more sunscreen, and 57.5% (n = 966) improved sunscreen measures. Web-based educational programmes raise public awareness, enhance prevention, and support early diagnosis of skin cancer. Teledermatology might contribute to reducing skin cancer mortality rates.
