Is there a link between deodorants or antiperspirants and breast cancer?

Stories claiming that using deodorants or antiperspirants increases the risk of breast cancer have been circulating on the internet and by email for several years. This issue also gets a lot of press coverage from time to time. Since these claims began to circulate some studies have looked at the possible link between deodorants/antiperspirants and breast cancer. But there is still no
good scientific evidence that a link exists.
