Scientists say more testing must be completed to make a conclusive ruling about the connection between tumors and parabens and aluminum - but at this point, they say there's little cause for concern.
Aluminum-based compounds are the active ingredients in antiperspirants. They block the sweat glands to keep sweat from getting to the skin's surface. Some research has suggested that these aluminum compounds may be absorbed by the skin and cause changes in estrogen receptors of breast cells. Because estrogen can promote the growth of both cancer and non-cancer breast cells, some scientists have suggested that using the aluminum-based compounds in antiperspirants may be a risk factor for the development of breast cancer.
Given the wide exposure of the human population to antiperspirants, it will be important to establish dermal absorption in the local area of the breast and whether long term low level absorption could play a role in the increasing incidence of breast cancer.
Aluminium is a metalloestrogen, it is genotoxic, is bound by DNA and has been shown to be carcinogenic. It is also a pro-oxidant and this unusual property might provide a mechanistic basis for any possible carcinogenicity.
At the moment, all the study has shown is that the body can absorb parabens and that these chemicals are found in some breast cancer tissue. It does not show that parabens can increase the risk of or cause breast cancer.
