Brief Summary

Esophageal squamous cell cancer (ESCC) is common in the developing world, and is the leading cancer diagnosis at Tenwek Hospital in southwestern Kenya. The investigators long-term goal is to understand the pathogenesis and risk factors for ESCC in Kenya, and to establish effective screening and prevention programs. The investigators hypothesize that asymptomatic esophageal squamous dysplasia (ESD) is common in their region, and the current protocol is designed to determine the prevalence of ESD in residents of southwestern Kenya.
