Tuesday Dec 9, 2008 (foodconsumer.org) -- Exposure to low concentrations of arsenic in drinking may increase risk of bladder cancer, a new study published in the Dec 2008 issue of Regul Toxicol Pharmacol.

Exposure to high levels of arsenic in drinking water has been known to be associated with increased risk of cancers including skin, bladder and lung cancer.

The study showed exposure to less than 100 to 200 mug of arsenic per liter of water increased the risk of bladder cancer in those who ever smoked by 24 percent.

For the study, Mink PJ and colleagues from Exponent, Health Sciences Practice in Washington DC meta-analyzed 8 studies of bladder cancer and low-level arsenic exposure.

The researchers also found that the risk of bladder cancer was slightly higher for never and ever smokers combined who were exposed to highest levels of arsenic compared to those who were exposed to lower levels.
