Melanoma rates in the US are consistently rising, and as several studies have suggested that there may be a raised incidence of melanoma among pilots and cabin crew, a team of researchers - led by Dr. Martina Sanlorenzo of the University of California - conducted a meta-analysis of 19 studies, involving over 266,000 participants.
The researchers found that the overall standardized incidence rate (SIR) of melanoma for flight-based occupations was 2.21. Specifically, pilots had a SIR of 2.22 and cabin crew had a SIR of 2.09. This result means that pilots and aircraft have twice the incidence of melanoma compared with the general population.
The authors acknowledge that their work is limited in that it utilizes observational and predominantly retrospective studies within its review. The authors were unable to adjust the findings of the studies used for potential confounders - other variables that may have influenced the results.
However, within the literature review, one study did not find any significant difference in the prevalence of melanoma risk factors - such as a history of sunburn or sunbed usage - between aircraft crew and the general population.
Other studies noted a correlation between increased incidence of melanoma within flight crew and increased numbers of flight hours, suggesting that occupational exposure to UV has more of an influence on melanoma incidence than leisure-activity exposure.
