Polycyclic aromatic hydrocarbon exposures and dietary risk of Esophageal squamous cell cancer in Uganda

The purpose of this study is twofold. First, it will seek to evaluate biomass fuel exposure as an ESCC risk factor by comparing personal carbon monoxide exposure among ESCC patients to that of age and gender matched controls with normal esophageal epithelia. Second, it will seek to examine food preparation methods and dietary patterns as risk factors for ESCC in southwestern Uganda.
