This is why I use paraben free deodorant.
akshewully…i rarely bother with antiperspirant, since the magic that is cross-sex transition-related hormone replacement therapy has removed most of my need for the stuff. BONUS!
Some people have all the luck. :P
are correlated with cause basically the same thing amirite? breast cancer” thing traces back to a 2004 study by UK molecular biologist Philippa Darbre. This study in no means settled the question:
Darbre’s research did not look at the concentrations of parabens in other areas of the breast or body tissues and Harvey [an editor of the journal that published the study] cautions that the significance of the chemicals in tumour tissue should not be over-interpreted.
Furthermore, the study only involved forty women with breast cancer—none without; and some who said they had never used antiperspirant or deodorant also had traces of paraben.
The reason parabens are associated with breast cancer is that, because of their chemical structure, they kind of act like estrogen does and estrogen levels are linked to breast cancer risk.
There are two questions we need to ask: how much are we exposed to compared to other estrogen-mimicking chemicals, and how powerful are parabens’ estrogenic activity? Well, this 1998 study (on rats) found that parabens are at least 100,000 times weaker than estradiol. A 2005 review of the literature, with a focus on studies done on humans, concluded that even in the worst-case scenario, exposure to parabens is much lower than exposure to the estrogen-mimicking chemicals (like phytoestrogens) that occur naturally in our food. This 2008 review also found that there is no evidence that parabens (or aluminum salts, the active ingredient in antiperspirants) are linked to breast cancer.
Here is a thorough overview of the research and the media alarmism.
P. S. Y’know what would really prevent—if not cancer, then people dying from cancer? Access to free, non-racist, non-fatphobic health care. But it’s a lot harder to do than just avoiding deodorant.
