Q. Why do people claim that using deodorant may cause cancer?

The link between deodorant and cancer has been the subject of much discussion, but there is currently no scientific evidence to corroborate such a claim.
There have been a number of studies examining the potential harm of chemicals in antiperspirants, most notably those containing aluminum. One study published in the 2014 journal PLoS One found that aluminum chloride hexahydrate (ACH), an active ingredient commonly found in antiperspirants, may have cytotoxic effects on human breast cells when applied to them under laboratory conditions. Other studies suggest that aluminum can interfere with hormone production and cause oxidative stress on breast cells as well. However, all these studies were performed in vitro or animal models; thus, they cannot be used to make conclusions about whether or not people who use deodorants will develop cancer in real life.
In addition to this research concerning ACH and other ingredients used in antiperspirants, some people believe that shaving armpits creates microscopic cuts which allow harmful chemicals from deodorant or antiperspirant products – like parabens – to potentially enter the bloodstream more easily. While it is true that parabens are present at low levels within many personal care products including deodorants (and are even being studied for potential uses as preservatives due to their antimicrobial nature) there is still no direct evidence demonstrating a causal relationship between using these products and developing cancer.
As we can see then, while it’s important for consumers to remain aware of any potentially hazardous substances present in consumer goods like personal care products so they can make informed decisions about what kinds of things they put against their skin — there is currently no scientific evidence suggesting that using commercial deodorant causes cancer.
