A content analysis of news coverage of skin cancer prevention and detection, 1979-2002
Unformatted Document Text:  Skin cancer news coverage 6 (Rigel, Friedman, & Kopf, 1996a) . The American Cancer Society estimates that in the year 2002 the incidence of newly diagnosed melanoma, excluding the pre-melanoma condition mealnoma in situ, is 53,600 cases with 7,400 deaths (American Cancer Society, 2002a) . There are numerous known risk factors, both genetic and environmental, for each of these three common skin cancers. For melanoma, basal cell carcinoma, and squamous cell carcinoma, there is a common causal pathway involving exposure to solar ultraviolet radiation or other sources of ultraviolet radiation, including medical treatments for skin disease and indoor tanning (Armstrong & Kricker, 2001; Spencer & Amonette, 1995) . Chronic intermittent and significant childhood exposure have a well established link to incidence of nonmelanoma skin cancer (i.e. basal and squamous cell carcinoma) (Rosso et al., 1996; Zanetti et al., 1996; Gallagher, Hill, Bajdik, Coldman et al., 1995; Gallagher, Hill, Bajdik, Fincham et al., 1995; Zaynoun, Ali, Shaib, & Kurban, 1985) , whereas the causation of melanoma is less clear and may be related more closely related to genetic factors, the presence of nevi (moles), and intense ultraviolet exposure episodes, especially during childhood (Zanetti, Franceschi, Rosso, Colonna, & Bidoli, 1992; Holman, Armstrong, & Heenan, 1986; Green, Siskind, Bain, & Alexander, 1985; Lew, Sober, Cook, Marvell, & Fitzpatrick, 1983) . Fair-skinned individuals are at increased risk for developing nonmelanoma and melanoma skin cancer, because their skin type has less melanin (skin pigment), which has a protective effect against skin cancer (American Cancer Society, 2002c, 2002b) . Because the primary risk factor for skin cancer is exposure to ultraviolet radiation, education and promotion of sun avoidance, use of sunscreens and sun protective clothing, and avoidance of indoor tanning could produce a significant decrease in the incidence of theses cancers.
