“…[28][29][30] Sunscreen are often considered as tanning aid, 1,31 and advertising sometimes persuade sun seekers that sunscreens may ensure acquisition of a ''safe tan''. In spite of uncertainties about their exact role in melanoma and BCC occurrence, and in spite of recommendations that sunscreen use should just be an adjunct to other more natural forms of protection, such as use of hats, shirts, and search for shade, sunscreens remain the most frequently used sun protection method, mainly among adolescents and young adults, while in the same time, younger adults declare to be more likely to sunbathe deliberately than other people.…”

Sunscreen use is often proposed for sun protection because of their ability to block UV-induced sunburns (the sun protection factor -SPF). Among suntan seekers, however, risk of cutaneous melanoma may be increased because of extended sun exposure duration. We made a systematic review of the evidence linking sunscreen use to sun exposure duration. Five observational studies found that when sun exposure was associated with willingness to get a tan or to stay longer in the sun (i.e., intentional sun exposure), sunscreen use was associated with duration of sun exposure 13-39% longer. Paradoxically, sunburns tend to be more frequent among sunscreen users, probably because of greater natural sun sensitivity. When sun exposure was not intentional, sunscreen use did not increase time spent in the sun. Two European double-blind randomized trials conducted among young sun seekers found daily sun exposure duration, especially sunbathing, 19-25% longer with use of SPF 30 than with use of SPF 10 sunscreens. One randomized trial in a holiday resort in France found a 3-13% increase in sun exposure duration with use of SPF 12 versus SPF 40 sunscreen. But, the SPF 12 groups used 3.6-4.2 more sunscreen than the SPF 40 group, and thus the actual SPF in the SPF 12 group was higher than in the SPF 40 groups. In conclusion, sunscreen use leads to longer duration of sun exposure when sun exposure is intentional, but not when sun exposure is non intentional. ' 2007 Wiley-Liss, Inc.

“…The association between sunlight exposure and skin cancer has long been known: Paul Gerson Unna first described in 1894 precancerous histopathologic changes of the skin occurring in sailors. 13 Cumulative lifetime ultraviolet light exposure and recent ultraviolet exposure are risk factors for SCC, whereas intermittent, intense exposure may be more important in melanoma, although this is not definitively proven.…”

Keratinocyte carcinoma is by far the most common cancer in the United States.Basal cell carcinomas and squamous cell carcinomas account for approximately 80% and 20% of cases of KC, respectively. The term nonmelanoma skin cancer is commonly used to refer to squamous cell carcinomas and basal cell carcinomas; however, other types of nonmelanoma skin cancer, such as adnexal tumors and sarcomas, are less common and differ in their cell type, behavior, and epidemiologic features from KC.1 Primary care clinicians are well positioned to diagnose KC and to educate patients about preventive measures such as sun protection and self-examination. Here we review epidemiologic data and strategies for prevention, diagnosis, and clinical management of KC. (CA Cancer J Clin 2003;53:292-302.)

“…7 The growth of the indoor tanning industry began in the 1970s. [45][46][47] Indoor tanning prevalence is highest among US adolescents with 24% of 13-to 19-year-olds reporting any use, and 11.7% reporting frequent use of $10 times. 48 A crosssectional US study also described similar findings with 24.6% of 15-to 19-year-old girls reporting having ever used tanning beds.…”

WHAT'S KNOWN ON THIS SUBJECT: The incidence of childhood and adolescent melanoma has been significantly increasing up to 2004. Risk factors (fair skin, light-colored hair/eyes, female gender, presence of nevi, family history, increased number of sunburns, and exposure to UV radiation) are associated with melanoma.WHAT THIS STUDY ADDS: This study describes incidence trends of melanoma diagnosed between the ages of 0 and 19 years and from 1973 through 2009 by gender, stage and age at diagnosis, primary site, and exposure to UV radiation. abstract OBJECTIVE: Childhood and adolescent melanoma is rare but has been increasing. To gain insight into possible reasons underlying this observation, we analyzed trends in melanoma incidence diagnosed between the ages of 0 and 19 years among US whites by gender, stage, age at diagnosis, and primary site. We also investigated incidence trends by UV-B exposure levels.METHODS: By using Surveillance, Epidemiology, and End Results (SEER) program data (1973-2009), we calculated age-adjusted incidence rates (IRs), annual percent changes, and 95% confidence intervals for each category of interest. Incidence trends were also evaluated by using joinpoint and local regression models. SEER registries were categorized with respect to low or high UV-B radiation exposure. RESULTS:From 1973 through 2009, 1230 children of white race were diagnosed with malignant melanoma. Overall, pediatric melanoma increased by an average of 2% per year (95% confidence interval, 1.4%-2.7%). Girls, 15-to 19-year-olds, and individuals with low UV-B exposure had significantly higher IRs than boys, younger children, and those living in SEER registries categorized as high UV-B. Over the study period, boys experienced increased IRs for melanoma on the face and trunk, and females on the lower limbs and hip. The only decreased incidence trend we observed was among 15-to 19-yearolds in the high UV-B exposure group from 1985 through 2009. Local regression curves indicated similar patterns.CONCLUSIONS: These results may help elucidate possible risk factors for adolescent melanoma, but additional individual-level studies will be necessary to determine the reasons for increasing incidence trends.
