Gastric cancer (GC) and esophageal cancer (EC) share risk factors, and the incidence trends reflect differences in etiology according to their subtypes. We aimed to describe the incidence trends of GC (by topography) and EC (by histological type) in northern Portugal for 1994-2009 and to estimate the incidence for 2015. We further analyzed exposure to the main risk factors for these cancers in the region over the last decades.
