Aggressive cancer type linked to common chemical exposure in new study
EATING LESS OF COMMON INGREDIENT EARLY IN LIFE MAY SLASH CANCER RISK DECADES LATER The highest PFOA exposure group had a 67% higher rate of ER-negative breast cancer.
Key points
- "This study, along with the accompanying meta-analysis of previous studies, provides evidence that two PFAS are related to a higher ER-negative breast cancer risk," study leader Alexandra White, Ph.D., a researcher at the National Institutes of Health, told Fox News Digital.
- MICROPLASTICS DETECTED IN MOST HEART ATTACK PATIENTS' BLOOD IN STARTLING NEW STUDY "They tend to be shorter-chain compounds and may be less persistent in our bodies and the environment, but we know little about how they may influence health outcomes, such as breast cancer," she said.
- Two "forever chemicals" have been associated with a higher risk of aggressive breast cancer, according to research from the National Institutes of Health (NIH).
The findings show an association, not proof of causation, between forever chemical exposure and breast cancer risk, as the authors noted that more research is needed.
Additional details
- research project called the Sister Study, which investigated environmental and genetic factors related to breast cancer.
- As this study focused mainly on older PFAS chemicals that have been largely phased out, the researcher said experts know "very little" about the PFAS that are replacing them, which could serve as a limitation.
- Tiffany Troso-Sandoval, a New York City-based breast and gynecological cancer specialist who worked at Memorial Sloan Kettering for more than 25 years, also acknowledged that forever chemicals can increase cancer risk.
- While patients with ER-negative breast cancer had higher levels of these compounds in their bodies, that does not prove the chemicals caused their cancers, according to Troso-Sandoval.
- ER-negative breast cancers tend to be "more aggressive" and have worse outcomes compared to breast cancers that respond to estrogen, according to a U.S.
