I get a lot of questions about the health and safety of aluminum in deodorant products. Are aluminum-containing deodorants safe to use, or do they increase the risk for breast cancer? There is no clear-cut answer to this question, but the short answer is….maybe?
Breast cancer has been on the rise since the 1960’s. Not only has the incidence of breast cancer increased, but it seems to be more common in the upper, outer portion of the breast than it used to be. Coincidentally, the use of aluminum-containing antiperspirants gained popularity in the late 1950’s, leading some people to believe there could be a correlation.
The data on this is conflicting, some studies do show an increased risk for breast cancer associated with aluminum deodorant use, some studies do not. But the evidence is clear that aluminum does get absorbed through the skin, and is found in high concentrations in the breast tissue of women who use it.
In one study, women who began shaving and applying aluminum deodorant before 16 years of age, and women who applied it more than once a day, seemed to be at higher risk for breast cancer.
So what does that mean for consumers? What should we do? Although there is no specific recommendation at this time to avoid aluminum-containing deodorants, many consumers are electing to do so, and there are now many aluminum alternatives on the market. Some such alternatives are made of baking soda, tapioca starch, copper, or magnesium.
When selecting a deodorant, whether it is aluminum-based or not, it is important to choose one that is not irritating. If you have sensitive skin, you may find the high pH of baking soda-based deodorants too irritating to your sensitive skin.
Other options to alleviate underarm sweating and odor that do not involve the use of underarm cosmetics include Botox injections, which can stop sweating for up to 6 months, or MiraDry, an in-office procedure that can potentially decrease or even stop underarm sweating permanently. These procedures should be done under the guidance of a board-certified dermatologist.
