Aluminum salts are found in some cosmetics in France, especially deodorants, which have been criticized in the past for their potential carcinogenic effect.
Aluminum salts are still specific. A new study published recently In the International Journal of Molecular Sciences, analyzed the effect of aluminum chloride, found especially in antiperspirants and cosmetics, on the development of breast cancer. According to the results of researchers, in certain quantities, even if they are low, their absorption can lead to the appearance of this disease.
This study, conducted by researchers from the Swiss Laboratory of Environmental Carcinogenesis, the Grangate Foundation and the University of Oxford, shows that “aluminum penetrates into breast cells and destabilizes the structure and number of chromosomes”, which can lead to breast cancer.
“There has been an epidemic of breast cancer for several years,” André-Pascal Sabino, professor of medicine and co-author of the study, told BFMTV.com, the causes of which scientists are looking for. And “there we all have the same very suspicious suspect.”
“lesions in exposed chromosomes”
Their study was conducted on hamster cells. “We used a model that has been fully validated in toxicology, and is used for cosmetic testing,” he explains. And according to their results, aluminum salts do not pass the test.
The scientist explains that if these components are applied “even in very small doses and for a limited time”, they will “pass through the skin and accumulate in the mammary gland”. This causes DNA breakage in the cells studied, “lesions in exposed chromosomes, a feature of tumors,” explains the scientist.
Cancers are “a disease caused by a normal cell that initially disrupts and transforms its program,” This is how the National Cancer Institute describes it.
In this sense, the study researchers suggest “particular attention should be paid to the long-term consequences of regular absorption of low doses.” [d’aluminium] Even co-authors Andre Pascal Sabino and Stefano Mandriotta, an oncologist at the Grangets Foundation, are calling for it to be banned.
“This, in my opinion, justifies the ban.”
This isn’t the first time aluminum salts have been highlighted for their carcinogenic effects.
These same Swiss researchers demonstrated in 2016 the effect of aluminum on breast cells. In their study, rats that were exposed to aluminum all developed highly aggressive tumors at times. Another study Published in 2017 in scalpelIt has been shown that daily, from an early age, use of underarm products increases the risk of breast cancer.
But if it is “suspected of their ability to promote the development of breast cancer, there is no evidence of a link between the use of deodorants or antiperspirants and the risk of breast cancer.” , So writes the National Cancer Institute. He also wrote that “the epidemiological data do not allow a definitive link to be established between cutaneous exposure to aluminum and the appearance of cancer.” National Medicines Agency (ANSM) in 2011.
“When you see such effects at very low concentrations, it’s a concern, and that in my opinion justifies the ban,” Stefano Mandriotta said. France information. “What we want is for us to stop talking about a harmless metal,” André Pascal Sabino replies.
Breast cancer is caused by “several risk factors that play a role in its development,” Explain health insurance. If some of them are identified (genetic predispositions, alcohol, tobacco …) others can be updated. This disease is the most common type of cancer among women, and it is estimated in France that one in eight women will develop breast cancer during her lifetime. In 2018, in France, nearly 59,000 new cases of breast cancer were discovered.
