Do Antiperspirants Cause Breast Cancer?

Do Antiperspirants Cause Breast Cancer?

A few years ago, I started taking a close look at our personal care products after learning that they may contain harmful toxins.  As a result, I opted to move away from commercial antiperspirants to something more natural – the Crystal deodorant rock.  I have been very happy with that decision, but at one point about two years ago I decided to try antiperspirants for a particularly active time.

I managed to use my old (in a new bottle of course) antiperspirant brand for about three days before throwing the bottle in the garbage and vowing to never use it again.  In just two days, I developed a series of hard knots in my underarms that were painful, itchy and very uncomfortable.  There is no question it was caused by the antiperspirant.  What surprises me is that I never had trouble before in many years of using the stuff.

There has long been anecdotal evidence and suspicions about a relationship between antiperspirants and breast cancer.  According to the National Cancer Institute (NCI), the studies done on the subject “have been completed and provide conflicting results.” 

A study of women with no history of breast cancer showed no increased risk from using deodorants or antiperspirants, or from shaving with a razor.  Another study of breast cancer survivors showed an earlier diagnosis in women who used underarm products and shaved.  The NCI recommends additional studies based on the conflicts between these studies.

As for me and my family, we will avoid the risk and stick with a natural product.  I have been using a Crystal deodorant rock for about four years now, and not only does it work quite well, it costs very little.  The $6 rock I bought two years ago has a good year left before I will run out.  Talk about savings!
