Can antiperspirants affect hormone levels and thus cause cancer?
There is no evidence that antiperspirants can affect hormone levels, and recent research has found no link between antiperspirant use and breast cancer. It is true that the hormone estrogen can promote the growth of breast cancer cells, and that rising levels of estrogen in women in developed countries may be responsible for the increase in breast cancer prevalence. However, this is not due to antiperspirant use.
