A new study shows methlyparaben and BPA, chemicals used in many consumer products, may reduce the effectiveness of cancer-fighting drugs like Tamoxifen.
September 13, 2011 – Researchers at the California Pacific Medical Center in San Francisco have just discovered that two common chemicals used in consumer products, methylparaben and Bisphenol A (BPA) are having a negative effect on cancer drug effectiveness. When both chemicals were combined and added to breast tissue cells, they rendered Tamoxifen ineffective. Tamoxifen is designed to kill both cancerous and normal cells.
Breast Cancer Drugs Blocked by Methylparaben and BPA
Reported in the San Francisco Chronicale, the latest study took noncancerous breast tissue cells and exposed them to Bisphenol A (BPA) and Methylparaben. When Tamoxifen was then introduced to stop and kill the cells, it was unable to do so. The results indicated to researchers that introduction of these chemicals made the cells take on cancer behaviors.
Most breast cancer drugs focus on minimizing estrogen, since most breast cancers are driven by estrogen. Both methylaparaben and BPA are known to disrupt hormone function. The Food and Drug Adminstration (FDA) confirms that Parabens are known to mimic estrogen and have been found in breast cancer tissue.
