I have done research on the link between antiperspirants deodorants and breast cancer. While researchers can't say for sure that deodorants cause breast cancer, they will say that results show that underarm shaving with the use of antiperspirants/deodorants may be related to breast cancer. The research studies on the link between the two have conflicting results. This is why i decided to link to the article so you ladies can decide for yourselves. It has a lot of really good info so please read it.
