Description: This paper discusses research on gastric cancers in Texas. Abstract: Although in recent years the prevalence of gastric cancers such as stomach and esophageal have dwindled slightly due to changes in diet, gastric cancers remain the second leading cause of cancer death worldwide. Past studies have shown a positive relationship between gastric cancers and increased intake of nitrites and nitrates. This study examines the geography of gastric cancer mortality in Texas counties in relation to the median nitrate concentration of groundwater wells. In addition, the correlations of gastric cancer mortality and race/ethnicity, gender, socioeconomic status, rural-urban residence, and employment in agriculture and mining are also explored. Whereas no correlation was found between median nitrate concentration levels and gastric cancer mortality, significant correlations were found with percent Hispanic population, percent urban, and percent White population. The study shows that in Texas, the relationship between nitrates and gastric cancer may not be as significant a factor as reported elsewhere.
