Abstract
OBJECTIVES: We sought to examine the associations between occupation and upper aerodigestive tract cancers at various anatomic sites. METHODS: The Swedish Family-Cancer Database was used to calculate standardized incidence ratios for different occupational groups, adjusted for age, period, and socioeconomic status. RESULTS: Male dentists showed an increased risk for tongue cancer; hairdressers had an increased risk for tongue and larynx cancers among men and pharynx cancer among women; launderers and dry cleaners showed an increased risk for pharynx cancer among men and lip cancer among women; outdoor occupations such as fishermen, seamen, transport, and construction workers showed increased risks for lip cancer. CONCLUSIONS: Although smoking and alcohol drinking can explain some of these results, increased risks found for dentists, hairdressers, and launderers and dry cleaners may partly be explained by their work-related exposures; increased risks of lip cancer in outdoor occupations can be explained by sunlight exposure.
