Have you ever gotten one of those scary chain emails telling you that your deodorant may cause breast cancer? It has to do with certain underarm products that contain preservatives called parabens. These chemicals can act like the hormone estrogen in the body. Estrogen is known to fuel certain breast cancers. Many breast cancers develop in the part of the breast closest to the armpit, where antiperspirants and other underarm products are used.
Now a new study shows that yes, there is evidence of parabens in 99% of breast tissue samples taken from women with breast cancer, but many of these women did not use any underarm products. Most major brands of deodorants and antiperspirants no longer contain parabens. Parabens such as methylparaben, ethylparaben, propylparaben, butylparaben, isopropylparaben, and isobutylparaben are also found in makeup, moisturizers, and hair care and shaving products. The findings appear in Journal of Applied Toxicology.
The new study does not prove that personal care products cause breast cancer. But “the fact that parabens were present in so many of the breast tissue samples does justify further investigation,” said Philippa Darbre, PhD, of University of Reading in the U.K., in a news release.
Don’t be scared of your cosmetics, she says. “Further studies need to be performed to determine if there is a relationship between parabens and breast cancer, but if one is concerned, there are natural products without parabens that could be used.”
