Aluminum Antiperspirants Likely Contribute To Breast Cancer
"New research indicates that the aluminum found within antiperspirants may contribute to breast cancer.
In a study published in the Journal of Applied Toxicology this month (Jan. 2012), researchers found that aluminum salts commonly found in antiperspirants exhibits oncogenic (cancer-causing) properties at extremely low concentrations.
In the authors' words:
"Aluminium salts used as antiperspirants have been incriminated as contributing to breast cancer incidence in Western societies. To date, very little or no epidemiological or experimental data confirm or infirm this hypothesis. We report here that in MCF-10A human mammary epithelial cells, a well-established normal human mammary epithelial cell model, long-term exposure to aluminium chloride (AlCl(3) ) concentrations of 10-300 µm, i.e. up to 100 000-fold lower than those found in antiperspirants, and in the range of those recently measured in the human breast, results in loss of contact inhibition and anchorage-independent growth." [emphasis added]
Research already shows that aluminum content is higher in nipple aspirate fluid in women with breast cancer-affected women versus a control group. Also, aluminum is one of a wide range of "metalloestrogens" that may stimulate the proliferation of estrogen-sensitive breast cells..."
