Compound Found In Plastic Drinking Water Bottles May Alter Gene Expression In Human Breast Cells

Topics: Health Issues

Plastic%20water%20bottles.jpgJust when you might think it was safe to drink the water in plastic bottles, along comes another chemical called BPA or bisphenol A. Now it looks as though you might want to think twice next time before you leave your plastic water bottle in a hot car, or even drink from a plastic bottle if you're genetically predisposed to breast cancer.

This, after a "Priority Report" in the latest issue of the journal Cancer Research, says that Bisphenol A (BPA), a chemical that leaches into food and beverages from many consumer products, especially plastic water bottles, causes normal, non-cancerous human breast cells to express genes characteristic of aggressive breast cancer cells:

Via ScienceDaily (Apr. 3, 2008) - [...] This new information about bisphenol A (BPA) is timely because the State of California is currently considering placing BPA on the Prop 65 list of hazardous chemicals, and State Senator Fiona Ma has proposed legislation that would ban BPA in products used by children.

The study was done by researchers at the California Pacific Medical Center Research Institute, in collaboration with the Stanford Genome Technology Center.

The findings are significant because BPA is found in many plastic water bottles, in plastic baby bottles, in the lining in food cans, as well as in sealants used by dentists to protect teeth.

"This is a very common compound that most of us are exposed to on a regular basis, often without even being aware of it," says William Goodson, M.D., Senior Clinical Research Scientist at the Institute and lead researcher on the study. "If it's true that exposure to BPA can cause normal, non-cancerous human breast cells to behave in ways that are more characteristic of aggressive breast cancer cells, this is very worrying."

Remember, the problem discussed here relates to BPA in plastic drinking water bottles, not DHEA or PET, which are not considered present at levels capable of affecting human cells - so far as is presently known.
