Rumors throughout the medical community and online community have suggested the claim that the use of deodorants or anti-perspirants may increase your risk for breast cancer.
Is this fact or fiction?

The YouTube video Antiperspirants, Deodorants, and Breast Cancer (2021) was created by Dr Eric Berg DC who is a Chiropractor. Dr. Berg (2021) reports the following medical claims in order to connect use of deodorants or anti-perspirants with an increase risk in breast cancer:
- most breast cancer develops in the upper quadrant of the breast which is close to the armpit, where deodorant is applied
- shaving increases the absorption of deodorant or anti-perspirant, which has toxins
- these toxins can include aluminum or parabens and can produce estrogen-like effects
Location of breast cancer
According to the American Cancer Society (2014), lymph nodes can be found in the upper outer quadrant of the breast, which is where about half of all breast cancers develop. As deodorants or anti-perspirants are used near the sweat glands, the American Cancer Society (2014) also reports that sweat glands are not connected to lymph nodes. This information concludes that there is no evidence to support the claim that the location of breast cancer is related to the location of where deodorants or anti-perspirants are applied.
Shaving
There is a claim that shaving can increase the absorption of deodorants or anti-perspirants which already may have cancer-causing substances. Dana K. Mirick (2002), a researcher affiliated with a cancer research center, reports of a population-based case-control study that was administered to patients who had a breast cancer diagnosis and patients who did not have a breast cancer diagnosis. The participants were women from 20-74 years old. The measures used were: the use of deodorants or anti-perspirants, product use for those who shaved with a blade razor, and application of either product after 1 hour of shaving. Statistical data reported that the risk for breast cancer did not increase with use of deodorants, anti-perspirants, or shaving. This information also concludes that there is no evidence to support the claim that the use of deodorants, anti-perspirants, or application of either after shaving can increase your risk of breast cancer.
Aluminum and Parabens
A study conducted by postdoctoral breast cancer researcher Raquel M. Rodrigues Peres in 2013 compared the aluminum levels in the central and peripheral areas of breast cancer with normal breast tissue to determine if there is a connection. Rodrigues-Peres (2013) used samples of breast tissue and a detection protocol called graphite furnace atomic absorption spectrometry (GFAAS) in order to determine aluminum levels. When comparing the two types of tissues, there was no significant difference in aluminum levels, which does not support that claim that there is a connection between exposure to aluminum and the risk of breast cancer.
Philippa D. Darbre (2004), a researcher affiliated with breast cancer research in the UK, reports a study that measured the mean concentration of parabens in samples of 20 breast tumors with use of scientific tools. Results showed that methylparaben represented 62% of the total paraben found in the extractions. Methylparaben is not found in deodorants or anti-perspirants.
The YouTube video Does Deodorant Cause Breast Cancer? (2018) is presented by the verified television show that features specialists and is hosted by medical doctors. Dr. Kristi Funk is a board-certified breast cancer surgeon. Funk reports that “no scientific evidence links these products” and references a literature review compiled in 2014 that researched the effect of aluminum-based compounds in deodorants or antiperspirants and health issues. Funk references other studies that support the research.
Conclusion
The YouTube video No, there’s no evidence that aluminum-based antiperspirants or deodorants cause cancer (2021) was created by VERIFY, a company that uses credible sources reported in this video. Credible sources here include the American Cancer Society, the National Cancer Institute at the National Institutes of Health, medical doctors, and dermatologists. This media clip supports the research.
Although media coverage surrounding this topic varies slightly, most media coverage and scientific research does not support the claim that deodorants or anti-perspirants can increase your risk of breast cancer, therefore debunking this myth.
