Reduction of daily-use parabens and phthalates reverses accumulation of cancer-associated phenotypes within disease-free breast tissue

“After treatment, I was in a free fall. The Anticancer Lifestyle Program caught me and gave me the support I really needed.”

“I never imagined the online course would be so comprehensive, enjoyable, and easy to follow! ”

My breast cancer diagnosis was a wake up call. The Diet module helped me to learn the science behind the food rules I followed while raising my kids and has motivated me to get back to that healthier way of cooking and eating. Thank you!

A recent study confirms that selecting for healthy personal care products does make a difference in exposure to endocrine disrupting chemicals.

Estrogenic overstimulation is carcinogenic to the human breast. Personal care products (PCPs) commonly contain xenoestrogens (XE), such as parabens and phthalates. Here, we identified the adverse effects of persistent exposure to such PCPs directly within human estrogen responsive breast tissue of subjects enrolled in a regimen of reduced XE use.

Pre- and post-intervention fine needle aspirates (FNAs) of the breast were collected from healthy volunteers who discontinued the use of paraben and phthalate containing PCPs over a 28 d period. Based on high-dimensional gene expression data of matched FNA pairs of study subjects, we demonstrate a striking reversal of cancer-associated phenotypes. Read about the study here.
