The various papers that were presented during this symposium touched on two of the most important aspects concerning melanoma because they dealt with epidemiology and genetics. Secondary prevention represents the most important step to cure melanoma patients once the disease has presented on a patient. It is clear that educational campaigns lead to greater awareness of the public and hence better prevention and earlier diagnosis. A second item is becoming more and more important in the field of prevention and early diagnosis, which is to understand the genetic basis of melanoma etiology and development. Studies concerning the familial clustering, for example, can lead to more careful monitoring of patients for other tumours and also lead to a basis for further research.
