Studies Link Aluminum in Deodorants to Breast Cancer

By now, we’re all aware of just how dangerous many of the chemicals commonly found in cosmetic and skin care products really are. Yet we are surrounded by these toxic compounds, with a recent study showing that one in eight of the 82,000 ingredients used in personal care products are hazardous and carcinogenic compounds. These industrial chemicals are also used as pesticides, and have negative effects on the reproductive and endocrine systems.



Aluminum is the foremost perpetrator.

A new study from the Journal of Inorganic Biochemistry found increased aluminum levels in 19 breast cancer patients. Long-term exposure to aluminum chloride, according to another study from the Journal of Applied Toxicology, has been linked to loss of contact inhibition and anchorage-independent growth. These effects were preceded by DNA double strand breaks. The study found that aluminum is not mutagenic in itself, but acts similar to an activated oncogene. An oncogene is a gene that is capable of transforming a normal cell into a tumor cell.

There are dozens of studies on aluminum toxicity, including several that tie aluminum to cancers. According to Kris McGrath, in an article published in Medical Hypothesis, “An unintentional, inadvertent, and long term hormone exposure may occur from transdermal absorption of sex hormones and pheromones (androgens) from axillary apocrine sweat gland obstruction by aluminum-based antiperspirants. The global rise in antiperspirant use parallels rises in breast and prostate cancer incidence and mortality rates. A multi-disciplinary literature based set of evidence is presented on how such a link is possible, to prompt confirmatory investigations in the pursuit of unmet needs in breast and prostate cancer etiology and prevention.”

Kris McGrath has found a link between the aluminum laden antiperspirant products and breast and prostate cancer.
