It just so happened that the cancer hike was exclusive to the same counties that had the highest concentration of natural gas production equipment and emissions – which are known to utilize a number of toxic solvents and other chemicals for their natural gas ‘fracking’ production according to some scientists.
It also so happens that while the rest of Texas and the U.S. on average is experiencing lower cancer rates, rates are up in these six counties: Denton, Hood, Johnson, Parker, Tarrant and Wise counties. These six counties contain about 3 million people within a 5,000 square mile area.
Breast cancer rates have been falling nationally over the last few years according to the National Cancer Institute. Between 1975 to 1999, breast cancers rose from 103 per 100,000 people to 141 per 100,000. Then the rates dropped since 1999, to 127 per 100,000 in 2008 – the last yearly data published by the Institute.
Meanwhile, according to the Texas Cancer Registry, breast cancer rates among these six counties in Texas has risen by nearly 20% from 2005 to 2008.
Research has increasingly found that breast cancer is linked to toxins. These have included smoking, synthetic hormones and other toxins according to the American Cancer Society. Most experts also agree that poor diet and lack of antioxidants also significantly relate to breast cancer. The National Institute of Environmental Health Sciences and the National Cancer Institute have been funding the Breast Cancer and the Environment Research Program, which studies causitive elements at laboratories on the east coast and west coast.
“Finding cancer clusters has a very limited application in understanding environmental exposure, since statistical research methods work better when studying things that are big,” Julia Brody, executive director of the Silent Spring Institute, told a Denton Record-Chronicle reporter. The Silent Spring Institute is a research group that studies breast cancer risk. The group has found a number of associations between toxins such as solvents and fuel compounds and breast cancer.
Natural gas production has been under fire for their use of potentially toxic chemicals, which they use during the process of drilling through shale using a process called “fracking.” Many states, such as New York, are seeking to limit the amount of potential exposure to these toxins during the production of natural gas. Robert F. Kennedy has reported recently on these efforts.
Medical researchers are currently trying to nail down the precise causes for the uptick in breast cancer rates among these counties – and are closely looking at natural gas production chemical exposure.
