Deodorants Don't Cause Breast Cancer

Contrary to Urban Legend, Underarm Products Pose No Cancer Risk

WebMD Health News

Oct. 15, 2002 -- An urban legend suggesting that antiperspirants cause breast cancer has been laid to rest by a new study. Researchers studying 1,500 women found no increased risk of breast cancer in women who used an antiperspirant or deodorant.

The absence of any visible connection may ease many women's fears, according to researcher Dana K. Mirick, MS, and colleagues of the Fred Hutchinson Cancer Research Center in Seattle, in a news release.

The study appears in the October issue of the Journal of the National Cancer Institute.

Researchers also found that many of the women were concerned that certain underarm products might contain harmful substances that could be absorbed into the system through nicks and cuts caused by shaving. However, the researchers found no association among shaving, use of underarm products, and breast cancer. In addition, there was no increased risk from using such products within an hour of shaving their underarms with a non-electric blade and breast cancer. -->
