Arsenic in groundwater is suspected to contribute to the rising incidence of kidney cancer in some parts of the USA. However, the association between low-level arsenic in drinking water and kidney cancer incidences is scarcely understood. A new study has investigated this association by analyzing 28,896 cancer cases across 240 counties in Texas. The study found that medium (1–5 ppb) and high (>5 ppb) arsenic levels in drinking water are associated with 6% and 22% higher incidence of kidney cancer , respectively, compared to low arsenic levels (<1 ppb).
Shockingly, each doubling of arsenic levels increased kidney cancer incidence by 4%. These findings suggest a link between low-level arsenic exposure through drinking water and kidney cancer. The study emphasizes the need for stringent regulation of arsenic levels in drinking water and targeted public health interventions. Should…
