What are we learning about the relationship between environmental toxicants and cancer? How should our regulatory system respond to this information?

Posted by Molly Rauch, MPH

Last week the National Toxicology Program, part of the US Department of Health and Human Services, released its 12th Report on Carcinogens. The release of the report made waves because it listed two substances not previously recognized by the US government as being linked to the development of cancer: formaldehyde (listed in the report as a known human carcinogen) and styrene (listed as reasonably anticipated to cause cancer in humans). Formaldehyde is used in construction materials, particle board, furniture, and as a preservative, among other uses; styrene is used in insulation, auto parts, ink cartridges, food packaging, and other products.

The 12th Report is a useful reminder that widely used substances, to which workers and consumers are routinely exposed and which have been in the marketplace for decades, are not necessarily safe. Indeed, in a context in which substances are welcomed into commerce with no information about their potential to cause cancer and other health problems, it is virtually inevitable that health problems will be detected after chemicals are in widespread use.

The report is also an important reminder of the power of a vested industry to influence science. The report had been delayed for four years – largely due to industry pressure. And while the report did list formaldehyde and styrene, what are the chemicals that the National Toxicology Program decided to leave out? And how was that decision made?

Cancer is a devastating, costly, and widespread disease. What are we learning about the relationship between environmental toxicants and cancer? How should our regulatory system respond to this information?

If a Superintendent does not know what the word Carcinogen means - he is not qualified for sure to be in charge of that job. Mindboggling.

As a victim and a witness to children injured by carcinogens - thank you for this article. I became founder of Children's EPA after I was seriously and permanently injured while teaching in Mississippi. I was prevented from protecting the children. An expose of the cover up revealed why - the chemicals involved had killed and injured half a million people in Bhopal India. Some of the chemicals in the spray on foam roofing and sealant were methyl isocyanate, toluene diisocyanate, benzene and xylene. The school superintendent's response was that he did not know the meaning of "carcinogen."
