On 6 January 2012, two researchers at the University of Geneva, Honorary Professor Stefano Mandriota and Professor André-Pascal Sappino, published a study in the Journal of Applied Toxicology which demonstrates the toxicity to human breast cells of aluminum salts which are found in 9 out of 10 deodorants. “In premenopausal women, mammary glands are more active and thus more sensitive to external agents,” states Prof. Sappino. Tests revealed that aluminum salts in amounts from 1,500 to 100,000 times less than contained in deodorants were found to be toxic to human breast cells. These cells proliferated when in contact with the aluminum salts which could lead to formation of tumors. The salts induced this effect only on breast cells. They were inoffensive to other types of cells.
Breast cancer has been on the rise over the last 40 years. The French-speaking part of Switzerland, which includes Geneva, has one of the highest rates of breast cancer in the world. Over the last 10 years (2000 – 2008) there has been an epidemic of breast cancer in young women less than 40 years old. In 2005, the Swiss Federal Office for Public Health (OFSP) had taken the position that there is no scientific evidence of a link between deodorants containing aluminum salts and breast cancer. The results of the 2012 study have not changed the OFSP’s position. “Scientific epidemiological studies have not proven the link between use of deodorants containing aluminum and increased risk of breast cancer; this has been confirmed by numerous scientific studies.” No precautionary measures are envisaged.
