Triclosan Breast Cancer - Triclosan promotes ER+ breast cancer cell growth
Keith D. Bishop, Clinical Nutritionist, B.Sc. Pharmacy -
Triclosan, the active ingredient in antibacterial soap, promoted breast cancer progression in the
Previous medical research demonstrated that Triclosan changes hormone levels and actions. In
this study researchers studied the effect of Triclosan on breast cancer cells in a laboratory test and in mice.
The breast cancer cells grown in the laboratory test tubes treated with Triclosan lead to cancer cell growth
associated with the estrogen receptor (ER) pathway.
The researchers implanted breast cancer cells into the bodies of mice. Breast tumor masses developed in the mice
that received Triclosan treatment for 8 weeks. The Triclosan had estrogenic activity and estrogen receptor (ER)
activity related to the cancer progression. Triclosan promoted breast cancer progression in the mice.
If you have ER+ breast cancer you should avoid the use of antibacterial soaps, body washes and shampoos. Similar
concerns exist for liver cancer.
