New Research: Common Cosmetic Ingredient, Paraben Esters, Present in 99% of Breast Cancer Tissues

New research has detected the presence of paraben esters in 99 percent of breast cancer tissues sampled. The study examined 40 women who were being treated for primary breast cancer. In 60 percent of cases, five of the different esters were present.

Parabens are chemicals with estrogen-like properties, and estrogen is one of the hormones involved in the development of breast cancer.

The study notes that:

“Variation was notable with respect to individual paraben esters, location within one breast and similar locations in different breasts.

Overall median values in nanograms per gram tissue for the 160 tissue samples were highest for n-propylparaben and methylparaben; levels were lower for n-butylparaben, ethylparaben  and isobutylparaben…

The source of the paraben cannot be identified, but paraben was measured in the 7/40 patients who reported never having used underarm cosmetics in their lifetime.”

Methyl paraben Propyl paraben Isobutyl paraben
Ethyl paraben Butyl paraben E216


These chemicals are commonly used in: Deodorants, antiperspirants, Shampoos, conditioners, Shaving gel, Toothpaste,
Lotions, Sunscreens, Make-up, Cosmetics, Pharmaceutical drugs, Food additives

Studies have shown that parabens can affect your body much like the estrogens, which can lead to diminished muscle mass, extra fat storage, and male gynecomastia (breast growth). Other studies besides the one featured here have also linked parabens to breast cancer. The US Environmental Protection Agency (EPA) has linked methyl parabens in particular to metabolic, developmental, hormonal, and neurological disorders, as well as various cancers.

How to Avoid Some of the Most Common Culprits

Avoiding parabens and other harmful chemicals requires becoming an avid label reader. Beware that products boasting “all-natural” labels can still contain harmful chemicals, including parabens, so make sure to check the list of ingredients. Another alternative is to make your own personal care products. In many cases it’s much easier than you might think. Michael DeJong, environmentalist and author of books on green living has a book called Clean Cures, which is chockfull of affordable, easy, natural remedies you can prepare at home…
