BREAKING: A new NIH study found women with the highest blood levels of two “forever chemicals” (PFOA and PFOS) had higher rates of ER-negative breast cancer, a more aggressive type with few known risk factors.
No clear link was seen with breast cancer overall. ⤵️
What to know:
➡️Blood was collected years before diagnosis from 3,700+ women whose sister had breast cancer
➡️The study shows a link, not cause and effect
➡️PFOA and PFOS have been largely phased out, but people can still carry measurable levels

BREAKING: The UK Health Security Agency has launched a national study measuring PFAS (“forever chemicals”) in people’s blood and urine.
It will also test for arsenic, bisphenols, lead, phthalates, and flame retardants. Initial findings are expected in 2027. ⤵️
Samples come from the existing Health Survey for England.
UKHSA says evidence gaps remain on what exposure levels mean for long-term health.
What we do know: Exposure is measurable.
Function members can access environmental toxin testing for:
➡️Lead
➡️Mercury
➡️Arsenic*
➡️Aluminum*
➡️BPA Exposure*
➡️PFAS Exposure*
*Add-On Test available at an additional cost.

BREAKING: A new study suggests good sleep may help support brain health in people with type 2 diabetes, heart disease, or stroke.
Caveats of the study: Sleep was self-reported, and the data shows a link, not cause and effect. 🧵
🧠 In UK Biobank data from 400,000+ adults, people with these conditions and a healthy sleep pattern scored slightly higher on tests of reasoning and processing speed than those with a poor sleep pattern.
🔎In a subset of about 35,000 who had brain MRI scans, they also had larger total brain, gray matter, and white matter volumes—a pattern generally associated with healthier brain aging.
AMA: “Is it perimenopause? What can your labs actually tell you?”
Function’s Women’s Health Medical Director, Dr. Tiffany Lester, is hosting a Reddit AMA on cycle changes, fatigue, sleep, mood, and weight in your late 30s and 40s. What your labs mean, what tracking over time can (and can't) tell you, and whatever else you want to know.

Is cannabis becoming part of the heart health conversation?
Preliminary research findings headed to the American Heart Association’s Scientific Sessions this month suggest a link between cannabis use and stroke risk. 🧵
➡️Researchers looked at self-reported cannabis use and history of stroke and heart disease.
➡️Findings are preliminary and not yet peer-reviewed.
➡️The study’s authors say it’s increasingly important to include cannabis in conversations about heart health—alongside other lifestyle habits.
Your habits are one part of your heart health picture. Your labs are another.
🔎Heart markers like ApoB, Lp(a), and hs-CRP can add context.
✅ Function members get access to these tests as part of 160+ lab tests.

A new JAMA Cardiology study found that adults 30-45 with high coronary artery calcium for their age and sex had a 5x higher estimated risk of dying of heart disease over 30 years.
Coronary artery calcium (CAC) is a sign of plaque in the arteries of your heart. It can build up over years before symptoms appear.
A Heart CT* measures it. 👉Members with out-of-range heart biomarkers may benefit from one.

BREAKING: A new study of over 52,000 healthy women ages 45 to 59 found modern menopause hormone therapy wasn't associated with higher heart disease risk.
Over an average of 12 years, 4.4% of women on therapy had a heart attack, stroke, or other heart disease, vs. 4.6% of women not on therapy.
These are early findings. ⤵️
The study is observational and not yet peer-reviewed. It will be presented at the American Heart Association’s Scientific Sessions Nov. 6–9.
Wherever you land on hormone therapy, knowing your heart risk adds context.
Lab tests that help measure it:
✔️ApoB
✔️Lp(a)
✔️hs-CRP
✔️Lipid panel
If any are out of range, a Heart CT* can add context by measuring calcium buildup in your heart’s arteries.
