Thread: "heavy metal" Antiperspirant

Aluminum is classified as a "heavy metal" and is thus a carcinogenic (thank goodness for spell check) My beef is..... every antiperspirant has aluminum in it! Armpits are ironically close to breasts maybe we shouldn't have daily doses of carcinogens going there and "brewed" all day everyday. Just a thought. Am I crazy? I haven't been able to find one that doesn't- any help?
