title: Prevention campaign against skin cancer.
abstract: BACKGROUND
  The melanoma incidence has increased over recent decades. Educational campaigns aim to encourage protection from the sun and early detection of melanoma.
  
  
  METHODS
  During a campaign in Switzerland, information on risk factors, sun protection and melanoma prevention was distributed. 10987 people completed a questionnaire regarding risk factors, and 2746 people were examined by a dermatologist.
  
  
  RESULTS
  Men had a higher risk as assessed by skin type, ultraviolet exposure, family history, number of moles and sunburns during childhood. Changes in moles were reported significantly more often by people with: (1). a positive family history (p < 0.0001); (2). multiple moles (p < 0.0001), and (3). sunburns during childhood (p < 0.0001). A precancerous or cancerous condition was suspected in 16% of individuals examined.
  
  
  CONCLUSIONS
  Early detection of melanoma can be achieved by this type of campaign. Primary prevention is a long-term approach and educational efforts targeting risk groups must be continued.
