It is believed that exposure to UV leads to skin cancers because the UV forms DNA photolesions that induce gene mutations (Pfeifer, 1997). Cutaneous melanoma (CM) and basal cell carcinoma (BCC) seem to be associated with intense intermittent exposure, whereas squamous cell carcinoma (SCC) seems to be related to cumulative exposure (Melville et al., 1991; Weinstock, 1993; Saraiya et al., 2004).
The importance of urban environmental design and configurations in influencing skin cancers depends on the epidemiology of these diseases. Gathering epidemiological data on non-melanoma skin cancers is difficult, in part because these diseases are not always included in cancer reporting registries (Weinstock, 1993). One indication of the importance of sun as a causative agent is indicated by the fact that incidence rates of all three skin cancers generally increase with decreasing latitude and with average cumulated UV-B irradiance, particularly for BCC (Leffell and Brash, 1996). Incidence of non-melanoma skin cancer in the southern U.S. is about double that in the north (Weinstock, 1993).

Complete Guide to Preventing Skin Cancer. We all know enough to fear the name, just as we do the words tumor and malignant. But apart from that, most of us know very little at all about cancer, especially skin cancer in itself. If I were to ask you to tell me about skin cancer right now, what would you say? Apart from the fact that its a cancer on the skin, that is.
