New research examining parabens found in cancerous human
breast tissue points the finger at antiperspirants and other cosmetics for
increasing the risk of breast cancer.
The research, which is also reviewed in an editorial
published in the Journal of Applied Toxicology,
looked at where breast tumors were appearing, and determined that higher
concentrations of parabens were found in the upper quadrants of the breast and
axillary area (armpit), where antiperspirants are usually applied.
Parabens are chemicals that serve as preservatives in
antiperspirants and many cosmetics, as well as sun lotions. Previous studies
have shown that all parabens have estrogenic activity in human breast cancer
cells.
The featured study by Barr et.al. discovered one
or more paraben esters in 99 percent of the 160 tissue samples collected from
40 mastectomies. In 60 percent of the samples, all five paraben esters were
present. There were no correlations between paraben concentrations and age,
length of breast feeding, tumor location, or tumor estrogen receptor content.
Paraben esters are as follows:
·
Propylparabens
·
Methylparabens
·
Buthylparabens
·
Ethylparabens
·
Isobuthylparabens
While antiperspirants are a common source of parabens, the
researchers note that the source of the parabens cannot be established, and
that 7 of the 40 patients reportedly never used
deodorants or antiperspirants in their lifetime. What this tells us is that
parabens, regardless of the source, can bioaccumulate in breast tissue.
And the sources are many. Parabens can be found in a wide
variety of personal care products, cosmetics, as well as drugs.
It appears through the skin is the most significant form of exposure; research shows that the liver
converts paraben esters taking into the body through drugs into harmless
substances.
The safety
of parabens has never been established. Its use is depended on a research on
rats in 1956.
Two esters
of Parabens are in my own body cream. I have always been convinced that lots of
additives in our care products and processed foods accumulate to cause us
problems.
In the villages
people are getting older in good health but the urban areas are filled with
middle aged people struggling with one form of disease or the other.
So please be
kind and share this information especially with women.
