Parabens and breast cancer

Parabens are Endocrine Disrupting Chemicals (EDCs) used as preservatives to stop the growth of microorganisms in cosmetics, personal care products and some processed foods. They can be ingested or absorbed through the skin and have been found in many body fluids and tissues, including in the breast. In laboratory studies, parabens were found to interfere with the female hormone oestrogen and increase the risk of mammary tumours in animals. However, only a limited number of human studies have been carried out and these are inconclusive regarding the possible link to breast cancer. Nonetheless, exposure to parabens should be reduced by seeking paraben-free cosmetics and personal care products. Regulations should also be tightened, especially for parabens officially recognised to be EDCs. Breast Cancer UK is calling for the phasing out and removal of EDCs from non-essential products.
