“…Radespiel et al in a report from Germany in 2009 described that outdoor jobs and contact with sunlight are mostly accompanied by BCC, a finding in harmony with the results of the present study (6). Similarly, in another study by Vishvakarman and Wong an association between outdoor job and skin cancer was demonstrated (9). The ratio of developing BCC to SCC was 3.1 in our study which is compatible with those of others.…”

Background: Non-melanoma skin cancers (NMSC) are the most common cancers worldwide. These cancers are not accompanied by high mortality however they lead to various complications. Evaluation of NMSC predisposing factors could result in preventive measures, improvement of quality of life and reduction of medical costs. Objectives: This study aimed to determine predisposing factors of non-melanoma skin cancers in the province of Qazvin (Iran). Materials and Methods: A total of 484 proven cases of NMSC were evaluated for demographic characteristics, clinical findings, pathological type, location of lesion, and the existence of known or possible predisposing factors such as skin type, exposure to sunlight, and family and drug history within a ten-year period from 2001 to 2011. Data were recorded in a questionnaire through interview and clinical examination of patients by a physician and a dermatologist, respectively. Data were analyzed using the SPSS version 16 software and statistical tests including t-test and chi-square tests. Results: Of the 484 patients, 294 (60.7%) were male and 190 (39.3%) were female. Most cases of carcinoma were found in basal cells (77.7%) and the rest of squamous cells. The most common sites of involvement were the head and scalp. The most frequent predisposing factors were working in the open air (70.7%), history of previous radiation for treatment of tenia capitis (26.1%), and chronic skin diseases such as burn eschar, chronic lesion, fistula and actinic keratosis (35.7%). The most prevalent Fitzpatrick skin phenotypes were II or III (75.4%). There were significant correlations between the incidence of NMSC and hookah smoking and oral contraceptive pill (OCP) consumption. Conclusions: Skin phenotypes II and III were the most common types found in the present study and this could be due to the higher frequency of these phenotypes among the study population. The lower incidence of NMSC in areas other than the neck and scalp could be associated with the importance of covering style used by the population under study. Known risk factors for the incidence of NMSC were also observed in the present study. A history of radiotherapy for treatment of tenia capitis was observed in a considerable percentage of patients, which could lead to the incidence of cancer several decades later. Further studies are needed to determine the role of hookah smoking and the use of OCP in the occurrence of NMSC.

“…So sunbathing at a beach for one day every year has a higher lifetime relative risk for SCC than having 40 NLO biopsies at a peak energy fluence of 500 Jm À2 in lifetime. Outdoor workers on the other hand, have an even higher relative risk for SCC ranging from 2.3-5.5, depending on outdoor profession and latitude of country [26,27]. Thus the risks for SCC from such circumstances are much higher than that from NLO imaging.…”

High power femto‐second (fs) laser pulses used for in‐vivo nonlinear optical (NLO) imaging can form cyclobutane pyrimidine dimers (CPD) in DNA, which may lead to carcinogenesis via subsequent mutations. Since UV radiation from routine sun exposure is the primary source of CPD lesions, we evaluated the risk of CPD‐related squamous cell carcinoma (SCC) in human skin due to NLO imaging relative to that from sun exposure. We developed a unique cancer risk model expanding previously published estimation of risk from exposure to continuous wave (CW) laser. This new model showed that the increase in CPD‐related SCC in skin from NLO imaging is negligible above that due to regular sun exposure. (© 2014 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

“…This has been accounted for in past research to determine annual exposures (28,29,30,31,32). The methodology of Vishvakarman and Wong (28) is modified for this research that assumes an annual UVE exposure is accrued by the summation of exposures received during normal working days in which the individual spends 1.5 hours traveling to, from and at work daily, and receives between 4 to 6 hours exposure during weekends and annual leave periods.…”

This study investigates the influence of tee time to determine the relative basal cell carcinoma (BCC) exposure calculations was used to determine BCC and SCC risk factors for golfers using a regular weekly tee time. Relative risk was found to be proportional to golf tee time with mid morning tee times generally presenting the greatest risk in each latitude range. The greatest contribution toward the risk of developing basal and squamous cell carcinoma was found to occur for golfers beginning weekly rounds mid to late morning, with specific risk factors of 1.47 (BCC) and 1.98 (SCC) in the Northern hemisphere compared with similar maximum risk factors of 1.51 (BCC) and 2.08 (SCC) in the Southern hemisphere occurring at comparable morning tee times.Differences in annual UVE exposure between the golfer and non-golfer were the largest determinant of BCC and SCC risk. Generally, these risks were found to decrease with lower latitude although contribution toward overall risk was influenced strongly by the global time zone of each studied golf course site.3
