A recent study shows: Certain antiperspirant ingredients harm breast cells
In recent decades more and more people are suffering from breast cancer in developed countries. At the same time, the number of cases has risen, in which breast cancer occurs in the outer part of the breast – near the armpits. This was announced by scientists at the University of Geneva.
These developments aroused suspicion a few years ago that certain ingredients in antiperspirant deodorants may play a role in the pathogenesis. So far there was too little data to speak for or against this hypothesis. Geneva researchers have now been shown that often used aluminum chloride (an aluminum salt) in conventional deodorants can damage breast cells.
Ingredient damages breast cells
The team led by biologist Stefano Mandriota and breast cancer specialist Andre-Pascal Sappino cultured models of human breast cells for the study. The cells were exposed to aluminum chloride – in doses 1,500 – 100,000 lower than in conventional deodorants. After a few weeks the researchers found that the cells were damaged.
Cells show abnormal behavior
The aluminum chloride resulted in an abnormal behavior in the cells, which can be compared to initial stages of tumor-like changes in cells. In addition the researchers found an increased number of so-called double strand breaks of DNA, which could also be consistent with the development of cancer.
The study results may not demonstrate that aluminum salts such as those used in conventional deodorants cause breast cancer, the researchers said. But they were a scientific proof that these substances are harmful to breast cells.
