First article says only that they found traces of the chemical
(parabens) in every tumor they studied. This same chemical is used as a preserative in deoderants. That fact and the fact that
parabens acts as a growth agent in breast cancers as does
estrogen.

Quote from the BBC article;

"Their detection in human breast tumours is of concern since parabens have been shown to be able to mimic the action of the female hormone oestrogen," she said.

"Oestrogen can drive the growth of human breast tumours. It would therefore seem especially prudent to consider whether parabens should continue to be used in such a wide range of cosmetics applied to the breast area including deodorants."

Dr Philip Harvey, European editor of the journal, said the findings should be interpreted cautiously.

"Further work is required to examine any association between oestrogenic and other chemicals in underarm cosmetics and breast cancer."


Nowhere does it say it causes Breast Cancer.
