    Selenium, an essential nutrient and potential cancer inhibitor, was studied in Texas. Selenium-rich areas showed lower cancer mortality, suggesting a link that warrants further investigation.

    Area of Science:

    • Environmental Science
    • Oncology
    • Geochemistry

    Background:

    • Recent research highlights selenium as an essential micronutrient.
    • Emerging evidence suggests selenium possesses natural cancer-inhibiting properties.

    Purpose of the Study:

    • To investigate the geographic distribution of selenium in Texas.
    • To compare selenium levels with age-adjusted cancer mortality rates across the state.

    Main Methods:

    • Selenium concentrations in Texas ground and surface water were analyzed as indicators of environmental selenium.
    • Water data was correlated with geographic cancer mortality rates.

    Main Results:

    • Most Texas water sources exhibited low selenium levels.

  • The Panhandle and West Texas regions showed higher selenium concentrations, linked to selenium-rich Rocky Mountain soil.
  • A general trend of lower cancer mortality was observed in selenium-rich areas compared to selenium-poor regions.

    • Conclusions:

    • The study suggests a potential inverse correlation between environmental selenium levels and cancer mortality in Texas.
    • Geographic variations in cancer-provoking factors were acknowledged, but the selenium pattern merits further research.
