Is it true that deodorants containing aluminum and antiperspirants provoke cancer?

It is widely believed that the use of deodorants and antiperspirants who have aluminum salts in their composition increases the risk of developing certain types of cancer. We checked whether such a fear is reasonable.

IN Internet Can Meet Articles, reportingthat from the use of drugs with aluminum salts can develop breast cancer. Explain This is the fact that “aluminum salts have an action similar to the human hormone estrogen. And the dependence between the levels of hormones, in particular estrogen, and the development of breast cancer is established accurately. Estrogen contributes to the growth of tumor cells. ” Approved Also, that, accumulating, aluminum salts are able to get even into breast milk.

In addition, publications on social networks scare The fact that the use of aluminum -containing cosmetics provokes Alzheimer's disease and other dangerous diseases. For example, they write that “aluminum negatively affects the metabolism, especially mineral, on the function of the nervous system, affects the reproduction and growth of cells. The most important clinical manifestations of neurotoxic action include impaired motor activity, convulsions, reduction or loss of memory, psychopathic reactions <...> [excess aluminum] causes tooth fluorosis and specific bone damage (bone fluorosis); It can cause or strengthen the neoplasms of bones. ” An additional argument of the opponents of aluminum is that before the mammography doctors urgently Recommend Do not use antiperspirants.

First you need to designate than a deodorant differs from antiperspirant. The deodorant eliminates an unpleasant odor, and the antiperspirant blocks sweating. Aluminum salts in cosmetics Create The “cork” inside the sweat duct, blocking the release of sweat outward, respectively, in the deodorant, these substances are simply not needed. However, many aluminum salts are contained. The main argument of the opponents of aluminum - study 2007 British chemist Chris Exli from the University of Kile. He studied samples of amputated tissues of the mammary glands of women who were diagnosed with breast cancer. Exli noted that the concentration of aluminum salts in them is higher than the norm in humans. The scientist suggested that it was the accumulation of aluminum that caused the development of cancer.

It is worth noting right away that it has been an actively actively Popularizes Disinformation that aluminum contained in vaccines leads to the development of heavy forms of autism in children. Now the Exli is actively Published On Instagram, with which it spreads inaccurate information and collects donations. In particular, one of the largest sponsors His activities are Robert Kennedy Jr., a well-known supporter of many conspiracy theories.

In addition to the publications of Exli, opponents of antiperspirants with aluminum refer to study 2016 Swiss scientists who demonstrated that the prolonged exposure to aluminum salts contributes to the growth of malignant neoplasms in mice. It is worth noting immediately: the authors of the publication stipulate in it that experimental data are limited. At the same time, there are many other studies that refute the connection of aluminum and malignant neoplasms.

Even before the publications of the works of Exli, in 2002, scientists Interrupted Volunteers aged 20 to 74 years: 813 women with breast cancer and 793 healthy. They were asked if they use an antiperspirant or deodorant, whether they are shaking the skin of the armpits and whether the cosmetic product is applied within the first hour after shaving. There was no statistically reliable difference. In 2006 study With a similar design, they repeated in Iraq. The groups were smaller: only 54 women with breast cancer and 50 women without it, but there was no longer possible to find some pattern. Scientists came to the conclusion that the preference of a cosmetic agent does not increase the risk of oncological disease, in contrast to the use of oral contraceptives and family history.

Research also Showthat the skin of the armpits absorbs an extremely small amount of aluminum - about 0.012%, this is several times less than that amount of aluminum that every day enters our body along with food. The most simple language Explained This is a dermatovenerologist Alexei Poyemsky: "To make cancer develop, you need not only to smease an antiperspirant, but there is it." Systematic review of 2014 Supplies Bottom line: neither aluminum, nor its oxides, hydroxides or soluble salts show any carcinogenic activity; There is no evidence of the connection of these substances and the risk of developing Alzheimer's disease; The substance and its derivatives do not have genotoxic activity.

American oncological society also Finds A simple explanation that most mammary tumors occur in the upper outer quarter (supporters of aluminum theory associate this with the proximity of the site to an armpit). In this part of the breast, the initially larger tissues of the mammary gland, and in other parts, the adipose tissue prevails, therefore, the chance of malignant degeneration is higher in itself. In a similar way, they break the argument that the probability of cancer is lower in men, because they are less likely to shave armpits. In fact, men of this very tissue of the mammary gland are also less than in women, therefore, cancer does not occur so often. Moreover proportion The risk is close to ideal: women have about 100 times the volume of mammary glands tissue, and their risk of breast cancer is approximately 100 times higher than in men. American oncological society also Notesthat parabens in the composition of antiperspirants also do not increase the risk of cancer. The position of the Society for the Study of Cancer of the United Kingdom consistent With the views of American colleagues. The Canadian cancer is also unanimous society and American national fund breast cancer.

Thus, long -term research in different countries and the positions of the largest oncological associations clearly indicate that the use of antiperspirants with aluminum salts in the composition does not increase the risk of breast cancer.
