A 2005 review of the data available at that time concluded it is biologically implausible that parabens could increase the risk of any estrogen-mediated endpoint, including effects on the male reproductive tract or breast cancer and that worst-case daily exposure to parabens would present substantially less risk relative to exposure to naturally occurring endocrine active chemicals in the diet such as the phytoestrogen daidzein. The American Cancer Society also concluded that there was insufficient scientific evidence to support a claim that use of cosmetics such as antiperspirants increase an individual's risk of developing breast cancer.
