• Recent research found higher concentrations of parabens in the upper quadrants of the breast and axillary area, where antiperspirants are usually applied, suggesting they may contribute to the development of breast cancer. One or more paraben esters were detected in 99 percent of the tissue samples collected from mastectomies. In 60 percent of the samples, all five paraben esters were present
  • Overall, topical application of personal care products containing parabens appear to be the greatest source of exposure to these estrogen-mimicking chemicals, far surpassing the risk of the aluminum in antiperspirants
  • Aluminum chloride—the active ingredient in antiperspirants—has been found to act similarly to the way oncogenes work to provide molecular transformations in cancer cells. Like parabens, aluminum salts also mimic estrogen, and bioaccumulate in breast tissue, which can raise your breast cancer risk
  • Despite the fact that parabens are used in such a wide variety of products, their safety is primarily based on a rat study from 1956, as modern toxicology studies are lacking, and not a single study on the chemicals’ carcinogenity follow acceptable regulatory standard carcinogenity study protocols, according to a recent review
