Aggressive cancer type linked to common chemical exposure in new study
New York Post ^ | Nov. 10, 2026

Two “forever chemicals” have been associated with a higher risk of aggressive breast cancer, according to research from the National Institutes of Health (NIH). Forever chemicals, known as PFAS, are a group of synthetic chemicals that break down extremely slowly and can build up in the environment and the human body.

PFAS have been used in nonstick cookware, upholstery and clothing, as well as some food packaging and personal care items. The study, published in the Journal of Clinical Oncology, found that women with higher blood levels of two types of PFAS — perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) — were more likely to develop estrogen receptor-negative (ER-negative) breast cancer.

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. Department of Health and Human Services (HHS) press release.

upholstery and clothing

I assume from flame-retardant chemicals.

Or if you live anywhere near a military basse that has poisoned the groundwater, like Eieleson AFB or Ft Wainwright.

This is the prospective case-cohort study (within the NIH Sister Study) that reported higher pre-diagnosis blood levels of PFOA and PFOS associated with increased risk of ER-negative breast cancer (HR 1.67 and 1.93 for highest vs. lowest quartile, respectively), with supporting meta-analysis findings. An accompanying editorial is also available on the same site.

So it’s a good thing I don’t cook, always sit on wood and leather chairs, and don’t use deodorant?

I never understood “flame-retardant clothing.” Who’s going to walk through fire unless you’re a fireman?

Likely from stain resistant coatings.

Polyester is Petroleum/Oil. I had a polyester jacket that MELTED when I accidentally touched it with something hot.

There was a company that made these PFOAs here in southern NH. They had a leak at their manufacturing plant. They had to pay to put all the people in the area on town water.
The PFOAs got into the water table.

Quite possibly. The full effect of the shot probably won’t be admitted for years.

Fire retardant clothing is required by some oil field companies.
I think it just required so if a fire burns someone the company cannot be sued for having unsafe conditions.
I have a ton of FRs from my oil field work in Wyoming and north Dakota
