New research show BPA can reduce the effectiveness of chemotherapy treatments. Not surprising since previous research shows BPA can cause cancer.
“In tests on breast cancer cells, researchers from the University of Cincinnati found that Bisphenol A (BPA) may protect cancer cells from dying off when they are exposed to anti-cancer drugs.”
UC researchers used the same low-dose amounts of BPA that are found in the normal adult.
“They found that BPA acts on cancer cells in a similar manner to estrogen. Estrogen stimulates the creation of proteins that protect cancer cells from chemotherapy drugs.
Researchers have long known about this estrogen-induced effect on chemotherapy. However, they have been puzzled by the fact that some women who have less estrogen in their system, such as post-menopausal women, can still be resistant to anti-cancer medications.
The researchers said the findings will help scientists determine why these and other cancer patients, such as those with advanced stages of the disease, are resistant to chemotherapy.”
Very interesting findings. Wonder what the FDA and their cronies in the plastics industry will say to dismiss this?
This is yet another study, in a long and growing list, that shows BPA is indeed harmful at even low doses considered “safe” by the FDA.
Banning BPA will certainly send a message to manufacturers (who are already feeling the pinch in the baby product industry) and the government, that we will not stand for this. BPA is commonly found in the lining of canned foods and soda cans, dental fillings, polycarbonate water bottles, polycarbonate baby bottles and likely lurks in other areas we do not even think about – medical equipment for one.
How do you avoid BPA? Typically, BPA is found in polycarbonate plastic containers – look at the bottom of the container, if a recycle #7 symbol is there, it very likely contains BPA. However, it does not ALWAYS mean BPA is present – i.e. some of those single serve fruit contains are layered plastic and must be labeled as #7. But if the plastic is translucent and hard like glass, it’s more than likely made of BPA. Avoid canned foods (except the Eden Organics line which use another technology and their cans are BPA-free) and canned sodas. If you formula feed—watch out, many formula cans are lined with BPA, so at minimum use a powdered formula and not a liquid.

Why do you discuss the problems of BPA in adults ie., breast cancer and then only discuss avoidance for babies?
Lewis, if you look at the articles on this topic, I have linked to many studies. Most studies are done on adults when there are human studies, as who would purposely subject their child to such things? But I talk about avoidance for everyone, not just babies. The last paragraph in the article goes into this and I have a couple posts on how to avoid BPA. We have cancer in my family, so we avoid canned soft drinks, canned food (except Eden Organics when I need it, as their cans are BPA-free), no polycarbonate plastic is in our house either…
Additonally, as far as studies go, there have been studies on test animals that do show effects of BPA on fetal and infant development, health and behavior.
hope that helps.
