Image via Wikipedia Parabens are chemical preservatives found in almost all cosmetics and body care products. They are used to inhibit the growth of bacteria and increase shelf life. A comprehensive study of women with breast cancer published in the January issue of the Journal of Applied Technology found parabens in nearly percent of all cancerous breast tumors. This evidence clearly links these chemicals to women's cancers. Researchers from the University of Reading in the UK found that virtually all -- 99 percent -- of the tissue samples collected from women participating in the study contained at least one paraben, and 60 percent of the samples contained no less than five parabens.

Parabens are a class of widely used preservatives in cosmetic and pharmaceutical products. Chemically, they are a series of parahydroxybenzoates or esters of parahydroxybenzoic acid also known as 4-hydroxybenzoic acid. Parabens are effective preservatives in many types of formulas. These compounds, and their salts, are used primarily for their bactericidal and fungicidal properties. They are also used as food preservatives. No effective direct links between parabens and cancer have been established. Parabens are active against a broad spectrum of microorganisms.
Because underarm antiperspirants or deodorants are applied near the breast and contain potentially harmful ingredients, several scientists and others have suggested a possible connection between their use and breast cancer 1 , 2. However, no scientific evidence links the use of these products to the development of breast cancer. Aluminum -based compounds are used as the active ingredient in antiperspirants. Some research suggests that aluminum-containing underarm antiperspirants, which are applied frequently and left on the skin near the breast, may be absorbed by the skin and have estrogen -like hormonal effects 3. Because estrogen can promote the growth of breast cancer cells , some scientists have suggested that the aluminum-based compounds in antiperspirants may contribute to the development of breast cancer 3.
