In a recent article I referenced a study saying that Bisphenol A (BPA) can cause Autism but it stretches so much furhter than that. Another study in the USA has now shown that this same toxin can cause Breast Cancer. Here is the article from the San Francisco Chronicle.
A new study of fetal exposure to BPA, a plastic additive found in some food packaging, shows that the chemical altered mammary gland development in monkeys.
The researchers reported that the changes they observed in the monkeys reinforce concerns that BPA – bisphenol A – could contribute to breast cancer in women.
The research was published Monday in the Proceedings of the National Academy of Sciences.
For this study, the researchers fed pregnant rhesus macaques a piece of fruit containing BPA every day during their third trimester of pregnancy. The monkeys’ blood levels of BPA reached about the average level that BPA has been observed in human blood in the United States, said Patricia Hunt, a geneticist at Washington State University and one of the study’s authors.
After female offspring of these BPA-exposed monkeys were born, the researchers looked at their mammary glands. They found changes in the glands that give rise to dense tissue – something that in humans is a risk factor for breast cancer, Hunt said.
Earlier studies by Ana Soto and Carlos Sonnenschein, also authors of the new study, found that exposing rodents to small amounts of BPA could change their mammary gland development and lead to precancerous and cancerous lesions when the animals exposed as fetuses became adults.
“We think that our results suggest that it is very likely that fetal exposure to BPA would also increase the propensity to develop mammary cancer in monkeys,” Soto said.
The sum of all the findings “strongly suggest that BPA is a breast carcinogen in humans and human exposure to BPA should be curtailed,” she said.
The Food and Drug Administration has said that BPA is safe. On March 30, the FDA rejected a petition by the Natural Resources Defense Council to ban it. The FDA then said that more studies were needed.
The American Chemistry Council said the new study was faulty and didn’t alter its view that BPA is safe. Other studies have convinced regulators in the United States, Europe and Japan that BPA isn’t a carcinogenic hazard, said the council’s Steven Hentges.
The ‘convenience’ of plastic is killing us slowly. It doesn’t pay to be LAZY!!!!
