Myth: Antiperspirants or deodorants can cause breast cancer

Fact: There's no conclusive evidence that using underarm antiperspirants or deodorants causes breast cancer.

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 certain answer to the question of whether these products cause breast cancer. But the evidence to date suggests these products don't cause cancer.

If you're still worried that your underarm antiperspirant or deodorant could raise your risk of cancer, choose products that don't have chemicals that worry you.
