As prevention for all types of skin cancer, it is recommended to avoid unnecessary and extended sun exposure, especially for persons with a sunburn sensitive skin type. So in sunny and tropic areas generally a consequent use of sunscreens on uncovered skin is necessary.

But skin cancer, less common, can also appear without excessice sunlight exposures, often in predisposed persons with a positive family history and increasingly often later in lifetime. In the attempt to avoid the fatal consequences of skin cancer, it is important to recognize the early forms of it and the skin cancer precursers and to recieve treatment early enough.

Secondary prevention If skin cancer had been found and was treated, the idea of follow up visits is also, to inform patients about avoiding new risks and also to detect signs of beginning new skin cancers as early as possible for effective treatment.
