An increased incidence of various types of skin cancer has been observed worldwide. Despite the importance of other predisposing factors, including genetic ones, excess or inadequate sun exposure throughout life is known to be the most important risk factor for the development of skin cancer, at earlier ages and in different skin phototypes.1 Daily and cumulative sun exposure is associated with an increased incidence of actinic keratosis and squamous cell carcinoma and some forms of basal cell carcinomas.1 Acute exposure, even if sporadic, to UV radiation, particularly in tropical climates and when the skin has not been progressively prepared for sun exposure, or exposure to tanning beds, is associated with higher incidence of basal cell carcinoma and melanoma.1,2 In fact, frequently people are exposed to high levels of UV radiation without recognizing not only the short-term but also the medium- and long-term risks.
