Norway's Own Screening Adviser Ran the Numbers: About One in 86 Screened Women Overdiagnosed

By its own adviser's estimate, Norway's mammography program overdiagnoses about one in 86 screened women, roughly three for every breast cancer death it prevents, while a 58-trial review finds early detection is no reliable stand-in for fewer deaths.

Women Who Cleaned Lost Lung Function at a Pace Compared to Smoking 10 to 20 Cigarettes a Day

Over 20 years, women who cleaned at home or for a living lost lung function faster than women who didn't. Tested scented products gave off carcinogens their labels never named, and single-chemical safety limits weren't built for the mixture under your sink.

When the Fat Comes Off, DDT's Half-Century-Old Residue Pours Back Into the Blood

Bariatric patients who shed 45 kilograms saw their blood levels of DDE, the breakdown product of DDT, more than double. The fat we're told to lose has been holding industrial chemicals since the 1970s.

The Calf Ache Medicine Shrugs Off Can Turn Deadlier Than Some Cancers

Advanced peripheral arterial disease kills 30 to 50 percent of patients within five years, a worse record than some cancers, yet most symptomatic patients in one large U.S. study never got the basic drugs they qualified for.

Feeling Fine in Pregnancy Was No Shield Against Dirty Air's Link to Postpartum Depression

Among 475 Mexico City mothers, each 5 microgram per cubic meter rise in fine-particle pollution during pregnancy tracked with 2.67 times the risk of depression symptoms that first appeared after birth. The link was stronger in women who reported little stress.

Autoimmune & Inflammation

Pesticides Outlawed in the 1970s Are Still in Women's Blood, and They Track With Chronic Inflammation

French scientists screened 45 banned or barely-regulated chemicals in 468 women's blood. Two pesticides cancelled decades ago still tracked with elevated inflammation, and the PFAS quietly pushed an immune signal down.

Investigations

The Fibroid Procedure That Spares the Uterus: Its Best Head-to-Head Evidence Was Paid For by the Device Maker

Radiofrequency ablation matched myomectomy on two-year symptom relief in a randomized trial. The device maker paid for that trial, and the durability question it cannot answer is the one that matters most.

Drugs & FDA

The FDA Warned a Generation Off Hormones. A Danish Registry Puts the Clot Risk in the Pill, Not the Patch.

Oral hormone therapy was tied to more clots, and to strokes and heart attacks at higher doses taken longer. The patches and gels carried no general increase. The warning that scared a generation of women off never drew the line.

They Drew Blood From 719 Women and Children in Rural Bangladesh. Every Sample Had at Least Two Mold Toxins.

Every one of 712 whole-blood samples from a cohort of 719 rural Bangladeshi women and children carried at least two mold toxins, and 84 percent of participants carried three or more, including one the liver converts into a carcinogen.

Investigations

97,000 Sibling Sets Later: Standard Air-Pollution Birth Studies Overshot One Risk and Buried Another

Comparing brothers and sisters born to the same mother stripped out many of the family-level confounders, and the scary preterm-birth links shrank while the growth-restriction link the conventional models kept underselling got stronger.

Autoimmune & Inflammation

Lupus Hits Nine Women for Every Man, and the Reason May Be Hiding in DNA Both Sexes Share

Scientists sequenced more than 1.25 million immune cells and found over 1,000 genetic switches set differently in men and women, with the female side tuned for stronger inflammation. It may help explain why lupus hits nine women for every man.

Investigations

Canada Went Looking for the Forever Chemicals Nobody Tracks and Found a Dozen of Them in Women's Blood

Scientists went hunting for the replacement and precursor PFAS almost nobody measures. In Canadian women's blood they found a dozen of them, riding alongside the 'banned' legacy chemicals that still turn up in nearly everyone.

Brain & Aging

For Twenty Years, Women Were Warned That Estrogen Raised Their Dementia Risk. Stanford's Autopsies Point the Other Way.

A randomized federal trial spent two decades warning that hormone therapy raised older women's dementia risk. A Stanford autopsy study just found the opposite association. The catch: both studied women who started the drug far too late to settle it.

A Map of 1.1 Million Lung Immune Cells Finds the Genetic Risk for Autoimmune Disease in Tissue, Not Blood

Researchers at La Jolla mapped genetic activity in 1.1 million lung immune cells and found about 1,000 genes whose activity is tuned by disease-risk variants only inside tissue, plus 1,700 that read differently in women than in men.

Brain & Aging

Same Diet, Same 15 Pounds: Only the Women Who Ate in an 8-Hour Window Got Sharper

Two groups of older women cut the same calories and lost the same 15 pounds over six months. The ones who packed eating into an 8-hour window still scored better on problem-solving, from a 47-person pilot that hasn't been peer-reviewed.

The GLP-1s That Barely Move the Scale Don't Cause Hair Loss, and That's the Clue Everyone Missed

Women on semaglutide shed hair at about twice the rate of men, and the weakest GLP-1s show almost no signal, which points the cause away from the follicle and straight at how fast the weight comes off.

Brain & Aging

Your First Pregnancy Rewires the Brain for One Baby. Your Second Rewires It for the Chaos of Two.

Amsterdam researchers scanned 110 women and found each pregnancy leaves its own mark, and the brain changes tied to maternal depression showed up months earlier the second time around.

Pregnancy Stations Killer T Cells in the Milk Ducts, and a Decade Later They Haven't Left

Melbourne researchers found that pregnancy stations killer T cells in the milk ducts, where they persist for at least a decade and track with better breast cancer outcomes. Now the race is on to summon them with a hormone shot instead of a pregnancy.
