RealFeedApp NIH study links PFAS to aggressive ER-negative breast cancer
NIH researchers found that higher blood levels of PFOA and PFOS increase the likelihood of developing ER-negative breast cancer, a more aggressive tumor type.
- Field
- cancer research
- What they did
- Researchers from the National Institutes of Health (NIH) conducted a meta-analysis and found a link between elevated blood levels of two PFAS chemicals (perfluorooctanoic acid and perfluorooctanesulfonic acid) and the risk of developing estrogen receptor-negative breast cancer.
- Why it matters
- This is important because estrogen receptor-negative tumors are a more aggressive type of cancer with few known risk factors, and the hormone estrogen does not help these cancer cells grow.
