Let me ask you a question. For how many years have you been wearing underarm deodorant? And, have you considered where all those chemicals are going? According to some researchers, the cumulative effect of daily deodorant use may be damaging to your health with an increased risk of getting cancer. I mentioned in an earlier post about the dangers of Triclosan (which is now banned in one U.S. State) read here. The jury is still out mind. But, I am uncomfortable with using the thought of using deodorants and now rarely use it. Are you concerned about using deodorants?
Cancer
Breast cancer is high on the list of concerns, not only because of the underarm’s close proximity to breast tissue but because several common ingredients in deodorants are estrogenic compounds. Estrogenic compounds have the ability to trigger some of the same effects as the body’s own hormone estrogen. One of estrogen’s roles in the body is to promote the growth of breast tissue, so an excess might lead to cancerous overgrowth. Aluminum is used as an antiperspirant to plug sweat ducts but is also know to be estrogenic.
In 2004, a study in the “Journal of Applied Toxicology” found parabens in 18 of 20 breast tumors; however, there was no examination of paraben levels in normal tissue to determine if a causal relationship truly existed. In 2006 a study published in the “Eastern Mediterranean Health Journal” studied the habits of 54 women with cancer and 50 without. Researchers found no association with use of deodorants. A larger study in 2003 in the “European Journal of Cancer” found the age of diagnosis of 437 breast cancer survivors was significantly earlier in women who shaved and used deodorants, the presumption being that nicks in the skin from shaving procured higher exposure. The diagnosis was even earlier in people who began these habits before the age of 16.
