Study proves link between aluminum deodorants and breast cancer
It has long been known that deodorants with aluminum can be dangerous. Swiss researchers have now provided further proof of the connection between such deodorants and the development of breast cancer.
Health risks from aluminum in deodorants
Years ago, experts pointed out health risks from aluminum in deodorants. Cosmetics containing aluminum are suspected to increase the risk of diseases such as cancer or dementia because of the metal they contain. According to the Federal Institute for Risk Assessment (BfR), however, this danger is not scientifically proven. However, Swiss scientists have gone one step further and have provided evidence of the relationship between aluminum deodorants and the development of breast cancer.
Increase in breast cancer cases in industrialized countries
As the researchers at the Clinique des Grangettes in Geneva wrote in a statement, the increase in breast cancer cases in industrialized countries that has been observed in recent decades remains largely unexplained. Although it is assumed that environmental factors make a significant contribution to the development of cancer in humans, no substance from the environment has yet been clearly identified as the cause of this "epidemic".
Aluminum salts can penetrate the skin
Because breast cancer predominantly forms in the outer areas of the mammary gland, i.e. near the armpit, the potential harm of deodorants has been under discussion for some time. Many deodorants contain high concentrations of aluminum salts that have been shown to be able to penetrate the skin. They can also accumulate in the mammary gland.
The alleged harmlessness of aluminum salts to human health has so far hardly been scientifically questioned. The research team led by Dr. Stefano Mandriota and Dr. André-Pascal Sappino from the clinic's oncology center has now succeeded in showing that breast cells from cultures with aluminum concentrations that correspond to the concentrations measured in the human mammary gland can cause tumors with very aggressive behavior in animals - i.e. Cancer that forms numerous metastases.
The use of aluminum is reminiscent of asbestos
The study, which was published in the International Journal of Cancer, also showed that aluminum salts cause an accumulation of mutations in the genome of the affected cells, which is a known feature of cancer cells.
According to the scientists, further studies are now needed "to better understand the role of aluminum cells in the development of breast cancer". However, the new findings represent another significant piece of evidence against this foreign substance and should prompt health authorities to restrict their use in the cosmetics industry.
The researchers pointed out that "the history of the use of aluminum salts is reminiscent of the dramatic fall in asbestos". The communication states: "The devastating effects of this inexpensive substance with attractive properties for industry have not been determined for decades in the usual toxicological screening tests in industry."
