A study linking breast cancer to deodorants by Dr. Philippa Darbre, a cancer researcher, from the University of Reading that was published in the Journal of Applied Toxicology, was reported in the NZ Herald Tuesday 13 Jan 2004. While the study does not absolutely prove a link between deodorants, or other cosmetics and breast cancer, it is the first study to detect the presence of parabens in breast tissue after being absorbed through the skin. Dr. Dabre points out that finding these (man-made) chemicals in human breast tumours is significant because they can mimic they way estrogen works to drive the growth of cancer. Over a 20 year period Dr. Darbre has earlier looked at the effects of aluminium in deodorants and has previously published over 70 research papers in peer-reviewed scientific journals and two books.

In Jan 2002, Dr. Darbre said (http://www.wen.org.uk/health/support_statements.htm) "I believe that there is strong evidence for an involvement of underarm cosmetics (antiperspirants/deodorants) in the cause of breast cancer, not least because of the gross disproportionate incidence of breast cancer in the upper outer quadrant of the breast, just the place where these chemicals are applied with ever increasing frequency" (reference: Darbre 2001, European Journal of Cancer Prevention 10, 389-393).
 
The incidence of breast cancer, has almost doubled in the last 25 years. Mortality figures from breast cancer are not rising. This suggests that current research is keeping death down amidst rising incidence. Surely now, the time has come to attempt to curb incidence. However, research into the prevention of breast cancer has little respect and, to my knowledge, no funding in NZ. Until the case is proven, I believe it is prudent to advise women (and men) to use only natural deodorants and be very careful to use cosmetics free of man-made chemicals.
 
Kinesiologists have advised clients to avoid deodorants containing aluminium for many years. Any ICPKP trained kinesiologist can test the effect of antiperspirants, deodorants or cosmetics on a client's meridian energy circuits and life-energy (chi, prana) and assist the person choose products which are neutral or enhance meridian function and life energy.
