Scientists are demanding that aluminum salts in deodorants be banned after investigation

Aluminum salts are present in some cosmetic products in France, especially in deodorants that have been criticized in the past for their potential carcinogenic effects.

Aluminum salts are still different. A new study recently published International Journal of Molecular Sciences, analyzed the effects of aluminum chloride on the development of breast cancer, especially in antiperspirants and cosmetics. According to researchers, their absorption, even in small amounts, can lead to the appearance of the disease.

The study, conducted by researchers at the Swiss Environmental Carcinogenesis Laboratory, Fondation des Grangettes and Oxford University, explains that “aluminum penetrates breast cells and disrupts the structure and number of chromosomes,” which can lead to breast cancer.

André-Pascal Sappino, a professor of medicine and co-author of the study, told BFMTV.com that “there has been a breast cancer epidemic that scientists have been looking for for several years.” And “there’s an equally suspicious suspect we all have.”

“Lesions on open chromosomes”

Their study was performed on hamster cells. “We used a model that was fully validated in toxicology and used to test cosmetics,” he explains. And according to the results, aluminum salts are not tested.

The scientist explains that “even in very small doses and for a limited time,” these components “will pass through the skin and accumulate in the mammary gland.” This leads to DNA damage in the cells under study, “lesions on the exposed chromosomes that are characteristic of tumors,” the scientist explains.

The National Cancer Institute said, “It’s a disease that goes wrong and changes the program, primarily from a normal cell.”

In this sense, the researchers suggest “paying special attention to the long-term consequences of regular ingestion of low doses.” [d’aluminium] For human carcinogenesis. “The authors call on André-Pascal Sappino and Stefano Mandriota, oncologist at the Grangettes Foundation, to ban it.

“This justifies the ban”

This is not the first time that aluminum salts have been selected for their carcinogenic effects.

The same Swiss researchers demonstrated the effect of aluminum on breast cells in 2016. Mice exposed to aluminum developed tumors during all studies, and were sometimes very aggressive. Another study published in 2017 Lancet, daily use of products from a young age and under the armpit, showed an increased risk of developing breast cancer.

However, “there is no evidence that deodorants or antiperspirants have been linked to the risk of breast cancer if they are suspected to promote the development of breast cancer,” the National Cancer Institute wrote. . In 2011, the National Drug Agency (ANSM) said, “Epidemiological data do not allow a definitive link between skin exposure to aluminum and the appearance of cancer.”

“When you see such effects at very low concentrations, yes, it’s a concern and I think that justifies the ban,” Stefano Mandriota told France Info. Andre-Pascal Sappino: “All we want is for us to stop talking about a harmless metal.”

Breast cancer stems from “several risk factors that play a role in its development,” Health Insurance explains. If some are identified (genetic predispositions, alcohol, tobacco …) others can be updated. The disease is the most common cancer in women, and in France it is estimated that about one in eight women will develop breast cancer in their lifetime. In 2018, about 59,000 new breast cancers were diagnosed in France.
