Two recent research have reopened the decades-long dispute in the scientific community on whether or not antiperspirant deodorants cause breast cancer.
Much attention has been paid to the potential oestrogen-like effects of aluminium, a common ingredient in antiperspirant deodorant.
Previous research has suggested that there is no correlation between aluminium in deodorants and an increased risk of breast cancer, but two recent articles have verified the carcinogenic potential of aluminium salts found in deodorants.
The studies were directed by Swiss academics André-Pascal Sappino and Stefano Mandriota and conducted by a team from the University of Oxford, the Fondation des Grangettes, and the Centre d'Onco-Hématologie.
To what conclusion can we attribute the research?
After conducting a battery of experiments on hamster cells, the researchers proved that mammalian cells, particularly those in the mammary gland (found in women's breasts), "rapidly assimilated this metal" when exposed to aluminium salts in vitro.
Researchers found that changes in the number and arrangement of chromosomes in these cells manifested as genomic instability within 24 hours of treatment.
According to the studies, this "confirms the carcinogenic potential" of aluminium on breast cells because it is also seen during malignant transformation brought on by known carcinogens.
Most common cancer in the world.
The World Health Organization estimates that by the end of 2020, there will be 7.8 million women alive who have been given a recent diagnosis of breast cancer (WHO).
Neither contagious nor infectious, the causes of breast cancer remain a mystery.
The World Health Organization estimates that around half of all breast cancer occurrences occur in women with no known risk factors for developing breast cancer other than being female and older than average (over 40 years).
Age, obesity, excessive alcohol use, a personal or family history of breast cancer, radiation exposure, tobacco use, and hormone replacement therapy after menopause all enhance a woman's chance of developing breast cancer.
According to the latest research, the findings pinpoint, for the first time, an environmental toxin that may be responsible for the rising rates of breast cancer.
Studies note that aluminium salts are employed in more than only antiperspirant deodorants; they are also present in other cosmetic items like sunscreen, and their incrimination in breast carcinogenesis is reminiscent of asbestos's past.
