MYTHS ABOUT CANCER II

Myth: Antiperspirants or deodorants can cause breast cancer?

Fact: There's no conclusive evidence linking the use of underarm antiperspirants or deodorants with breast cancer, according to the National Cancer Institute. 

Some reports have suggested that these products contain harmful substances such as aluminum compounds and parabens that can be absorbed through the skin or enter the body through nicks caused by shaving. No clinical studies have yet given a definitive answer to the question of whether these products cause breast cancer. But the evidence to date suggests these products don't cause cancer.
