Disparity of Bladder Cancer Incidence Among Male Workers Across Industries

Abstract

Bladder cancer is the most common malignant neoplasm that develops in the urinary tract and the ninth most common cancer worldwide among newly diagnosed cancers. Although workplace hygiene has improved and carcinogen exposure has decreased, several occupations still show an increased risk of bladder cancer. BackgroundThis study aimed to investigate the bladder cancer risk across workers' industries.MethodsThis study was conducted using Korean National Health Insurance claims data. Workers were included in this study to build a retrospective cohort of the entire working population. Workers' industries were divided into 77 industries according to the Korean Standard Industry Classification division category. The standardized incidence ratio was calculated by comparing 77 industries according to the Korean Standard Industry Classification with the educational public officer.ResultsBladder cancer risk was particularly high in the following industrial sectors: passenger land transport, except transport via railways; sea and coastal water transport; restaurants and mobile food service activities; telecommunications; and computer programming, consultancy, and related activities.ConclusionsOur result provides evidence regarding the disparity of bladder cancer incidence among male workers across industries.
