Antiperspirant Use and Breast Cancer

The FDA is aware of concerns that antiperspirant use -- in conjunction with underarm shaving -- may be associated with increased risk of developing breast cancer. FDA continues to search scientific literature for studies examining this possible adverse drug effect. Unfortunately, there are many publications that discuss the issue but very few studies in which data have been collected and analyzed. Overall, the studies that contain data are inconclusive in determining whether antiperspirants, in any way, contribute to the development of breast cancer. FDA hopes that definitive studies exploring breast cancer incidence and antiperspirant use will be conducted in the near future.
