What's hiding in your home? The common chemicals linked to breast cancer

An NIH study found a link between exposure to PFAS chemicals (PFOA, PFOS) and an increased risk of ER-negative breast cancer. Women with high levels of PFOA showed a 67% increase in risk, and with PFOS a 93% increase. These chemicals are found in everyday products like non-stick cookware and food packaging.

A new study by the U.S. National Institutes of Health (NIH) has found a link between exposure to common PFAS chemicals and an increased risk of aggressive ER-negative breast cancer. The study, published in the Journal of Clinical Oncology, focused on two types of PFAS: PFOA and PFOS. It found that women with higher blood levels of these chemicals were at greater risk of developing ER-negative breast cancer, which is considered more aggressive with limited treatment options. In the highest exposure group for PFOA, there was a 67% increase in ER-negative breast cancer rates, and in the highest PFOS exposure group, a 93% increase. The researchers emphasize that this is a statistical association, not direct proof of causation. These chemicals are found in many everyday products, including non-stick cookware, food packaging, and cosmetics. The article includes recommendations for reducing exposure, such as testing drinking water quality and preferring stainless steel cookware.
