Question: Can wearing deodorants and antiperspirants cause breast cancer?
Answer: There has been tons of warnings circulated through email and the internet that the use of deodorants and antiperspirants can cause breast cancer. The suggestion is that a chemical is absorbed through the skin through a shaving nick or cut, and causes breast cancer.
According to the National Cancer Institute, "researchers at the National Cancer Institute (NCI) are not aware of any conclusive evidence linking the use of underarm antiperspirants or deodorants and the subsequent development of breast cancer. The U.S. Food and Drug Administration, which regulates food, cosmetics, medicines, and medical devices, also does not have any evidence or research data that ingredients in underarm antiperspirants or deodorants cause cancer."
