I am careful about selecting my sources of information—especially on the Internet, which is rife with misinformed interpretations and conclusions about research studies. I wasn't "given wrong information" nor was I calling people animals. I was pointing to one research study that successfully established a clear correlation between cancer and highly concentrated paraben consumption in test animals while you are pointing to another study that established only an association with parabens found in human breast tissue. The study on human breast tissue did not establish a clear-cut correlation (let alone causation) due to faulty research methods in failing to establish a control sample of identically evaluated healthy tissue. This particular study is also referenced on the website I linked above.
And yes, I mentioned parabens' estrogen-mimicking behavior in my review, and it is also discussed on the linked web page I provided above. I did not rehash everything here because I thought people would take the time to read the links if they were interested. Regarding the estrogen-mimicking behavior of parabens, one would have to take extremely concentrated, huge dosage amounts of parabens for them to have that type of effect in the human body. That would be near to impossible to obtain those kinds of levels in a normal diet or in normal cosmetic application since the percentage amounts in those products are so small.
I am not, by any means, an advocate or staunch defender of parabens. I always advocate taking precautions with anything that could prove dangerous. I just like to separate the actual facts from speculation. I was only stating that at this point there is only speculation but no clear-cut proof that parabens cause cancer when consumed or applied in the low levels approved by the FDA. Does this mean that I think they are 100% safe? No, but I don't want to falsely promote undue hysteria about it. But I definitely view parabens with suspicion because of the number of people who have developed a topical sensitivity to them and will choose a product without them if I'm given a choice.
Sadly, however, it would be nearly impossible to eliminate them from consumption altogether (either ingested or topically applied) since they are so prevalent in the marketplace. Anyone who is concerned about parabens should start reading their food labels (not just their cosmetic labels) and petitioning the FDA to eliminate any amount of parabens in their food. Parabens have been used in food for decades, which can explain the presence of parabens in body cells and in urine. Parabens are even found in infant-care items. But until further research shows a positive correlation between cancer and the currently approved dosage amounts for human consumption and topical application, the FDA will not take these petitions seriously.
The following is from the FDA's statement about parabens (which is linked at the bottom of the web page that I linked in my earlier post above, but here is the direct link as well as a quote from the page): link
"Are there health risks associated with the use of parabens in cosmetics?
The Cosmetic Ingredient Review (CIR) reviewed the safety of methylparaben, propylparaben, and butylparaben in 1984 and concluded they were safe for use in cosmetic products at levels up to 25%. Typically parabens are used at levels ranging from 0.01 to 0.3%.
On November 14, 2003, the CIR began the process to reopen the safety assessments of methylparaben, ethylparaben, propylparaben, and butylparaben in order to offer interested parties an opportunity to submit new data for consideration. In September 2005, the CIR decided to re-open the safety assessment for parabens to request exposure estimates and a risk assessment for cosmetic uses. In December 2005, after considering the margins of safety for exposure to women and infants, the Panel determined that there was no need to change its original conclusion that parabens are safe as used in cosmetics. (The CIR is an industry-sponsored organization that reviews cosmetic ingredient safety and publishes its results in open, peer-reviewed literature. FDA participates in the CIR in a non-voting capacity.)
A study published in 2004 (Darbre, in the Journal of Applied Toxicology) detected parabens in breast tumors. The study also discussed this information in the context of the weak estrogen-like properties of parabens and the influence of estrogen on breast cancer. However, the study left several questions unanswered. For example, the study did not show that parabens cause cancer, or that they are harmful in any way, and the study did not look at possible paraben levels in normal tissue.
FDA is aware that estrogenic activity in the body is associated with certain forms of breast cancer. Although parabens can act similarly to estrogen, they have been shown to have much less estrogenic activity than the body’s naturally occurring estrogen. For example, a 1998 study (Routledge et al., in Toxicology and Applied Pharmacology) found that the most potent paraben tested in the study, butylparaben, showed from 10,000- to 100,000-fold less activity than naturally occurring estradiol (a form of estrogen). Further, parabens are used at very low levels in cosmetics. In a review of the estrogenic activity of parabens, (Golden et al., in Critical Reviews in Toxicology, 2005) the author concluded that based on maximum daily exposure estimates, it was implausible that parabens could increase the risk associated with exposure to estrogenic chemicals.
FDA believes that at the present time there is no reason for consumers to be concerned about the use of cosmetics containing parabens. However, the agency will continue to evaluate new data in this area. If FDA determines that a health hazard exists, the agency will advise the industry and the public, and will consider its legal options under the authority of the FD&C Act in protecting the health and welfare of consumers."
