How a study on hormonal contraception and breast cancer was distorted
As misinformation about women’s health spreads faster than ever, doctors say new research on the risks of hormonal birth control underscores the challenge of communicating nuance in the social media age.
The study, which was conducted in Sweden and tracked more than 2 million teenage girls and women less than age 50 for more than a decade, found that hormonal contraception remains safe overall, but also found small differences in breast cancer risk based on the hormones used in the formulation.

In addition, the researchers observed a small, short-term rise in breast cancer diagnoses among current or recent users. Those findings are consistent with prior large studies, including a 2017 Danish registry analysis and a 2023 meta-analysis.
It was published online on October 30 in JAMA Oncology.
Doctors say these study results won’t change how they advise patients and that women should not stop using their birth control.
Still, TikTok is flooded with factually incomplete warnings that contraceptives cause cancer and are as dangerous as smoking. Reproductive health advocates warn that studies like this can easily be taken out of context online and be reduced to a single alarming number.
Case in point: The study reported that women who had used hormonal birth control had about a 24 percent higher rate of breast cancer than women who hadn’t. But because breast cancer is still uncommon in younger women, that works out to an increase from roughly 54 to 67 breast cancer cases per 100,000 women per year – about 13 extra cases per 100,000 women, or about one extra case per 7,800 users of hormonal contraceptives per year.
Co-authors Asa Johansson and Fatemeh Hadizadeh, epidemiologists at Uppsala University, said the rise is modest and short-term, with risk highest during current use and fading within five to 10 years after stopping.
Rachel Fey, interim co-CEO of Power to Decide – a group whose mission is to provide accurate information on sexual health and contraceptive methods – said that kind of nuance is exactly what tends to disappear on social media.
“I get really angry at this because it’s designed to scare people like me away from birth control, which has made my life so much better in so many ways,” she said. “It’s really frustrating … especially when it’s given without context. And then in this era of social media, it can just take off without anybody who knows what they’re talking about providing that context.”
The researchers also found the risk was slightly higher with certain progestins such as desogestrel – found in combined oral contraceptives like Cyred EQ, Reclipsen, Azurette, and Pimtrea – but did not increase with others, such as medroxyprogesterone acetate injections, sold under the brand name Depo‑Provera.
How to interpret the findings
Some experts say the results should be viewed with care because the study counted both invasive breast cancers and early, noninvasive lesions known as in situ tumours, growths that may never become life-threatening. Including these precancerous cases could make the overall risk of clinically significant disease appear higher than it is.
“A substantial proportion of the ‘cases’ would never have progressed to invasive breast cancer,” said Lina S Morch, a senior researcher and team leader at the Danish Cancer Institute. Morch was not associated with the Swedish study. She added that experts should wait for more data separating early-stage and advanced cancers before making new rules or warnings about specific hormones.
The doctor-patient conversation
Even as scientists debate how to interpret the finer points of the data, physicians emphasise that for most patients, the study reinforces what they already discuss in the exam room: That hormonal birth control is broadly safe, and decisions should be tailored to each woman’s needs and values.
Katharine White, chief of Obstetrics and Gynaecology at Boston Medical Center, said this study won’t change how she talks to her patients.
“When counselling patients about their contraceptive options, I focus on their past experiences with birth control, their medical history, and what’s important to them about their birth control method and pregnancy planning (if applicable),” White wrote in an email. “Side effects and risks of methods are already a key part of my counselling about both hormonal and non-hormonal methods.”
Other doctors noted there are other contraceptive options.
Eleanor Bimla Schwarz, chief of General Internal Medicine at Zuckerberg San Francisco General Hospital, said, “For those who prefer hormone-free contraception, the copper IUD offers safe, convenient, highly effective contraception for over a decade after placement, and is rapidly reversible when pregnancy is desired,” referring to a type of long-acting intrauterine device.
Mary Rosser, director of Integrated Women’s Health at Columbia University Irving Medical Center, said this was a large, high-quality study that looked at many types of hormones over many years. But she added that doctors shouldn’t change their advice yet.
Johansson and Hadizadeh stressed that the results should guide shared decision-making, not cause alarm. “It may be reasonable to consider formulations associated with lower observed risk in our data,” they said. They noted that products containing medroxyprogesterone acetate, drospirenone, or levonorgestrel were linked to lower risk, while long-term use of desogestrel-only contraceptives might be best avoided when other options fit.
Keeping the risk in perspective
Hormonal birth control provides many health benefits beyond pregnancy prevention. It can lighten heavy periods, ease pain from endometriosis, and lower the risk of ovarian and uterine cancers for years after stopping. Morch noted that even small risks are worth discussing, but said decisions should be guided by women’s “values and preferences”.
White said it’s important to see the big picture. “The risk of an unintended pregnancy is 85 percent for people who do not use contraception – so any risks of birth control need to be weighed against the risk of an unexpected pregnancy,” she wrote.

British Actors and Other Performers Back Industrial Action Over AI After Landslide Vote
Actors and other performers working in film and TV in the U.K. have voted by a landslide to refuse to be digitally scanned on set in order to secure artificial intelligence protections.
Member of performers union Equity working in film and TV voted in a ballot on AI protections, and decided by a massive majority that they are willing to take industrial action over AI. The ballot asked: “Are you prepared to refuse to be digitally scanned on set to secure adequate AI protections?,” and 99.6% of them responded “Yes.”
Equity commented: “Members are increasingly concerned about the use of their voice and likeness, including being digitally scanned on set. Equity is fighting for protections for performers based on the principles of explicit consent, transparency of terms, and fair remuneration for usage.”
The ballot turnout was 75.1%, with eligible voters made up of Equity’s membership working in film and TV – 7,732 actors, stunt performers and dancers.
The ballot was indicative, which means it is not binding and does not legally cover Equity members to take industrial action – for that, a statutory ballot is needed. However, the result shows the strength of feeling among performers about AI, and indicates they are prepared to refuse to be digitally scanned on set – a form of action short of a strike.
Equity is currently negotiating the agreements it holds with Pact, the trade body representing the majority of film and TV production companies in the U.K., to set minimum standards for pay, terms and conditions for performers working in the sector.
Equity will now write to Pact with the results and demand they come back to the negotiating table with a better deal on AI. If Pact refuses to enshrine the AI protections the union is seeking in the agreements, Equity will hold a statutory ballot for industrial action.
Equity’s general secretary, Paul W. Fleming, said: “Artificial intelligence is a generation-defining challenge. And for the first time in a generation, Equity’s film and TV members have shown that they are willing to take industrial action.
“90% of TV and film is made on these agreements. Over three quarters of artists working on them are union members. This shows that the workforce is willing to significantly disrupt production unless they are respected, and decades of erosion in terms and conditions begins to be reversed.
“The U.S. streamers and Pact need to step away from the brink, and respect this show of strength. We need adequate AI protections which build on, not merely replicate, those agreed after the SAG-AFTRA strike in the U.S.A. over two years ago.
“The union believes this can be resolved through negotiation, but 18 months of talks have led us to this stalemate. With fresh AI proposals, significant movement on royalties, and a package of modern terms and conditions, Pact and allied producers can turn this around. The ball is in their court when we return to the table in January.”

UK police arrest four people for pro-Palestine ‘Intifada’ calls
Arrests made at protests supporting imprisoned Palestine Action hunger strikers, as Gaza death toll surpasses 70,000.
Published On 18 Dec 2025
Police in the United Kingdom have made their first arrests since announcing their intent to crack down on people making public calls to “globalise the Intifada” after Australia’s Bondi Beach attack, speciously linking largely peaceful protests against Israel’s genocidal war with a deadly targeting of a Jewish festival.
London’s Metropolitan Police posted on X late on Wednesday that it had made four arrests at pro-Palestinian protests held outside the Ministry of Justice in Westminster, “all involving the alleged shouting or chanting of slogans involving calls for intifada”.

The arrests were made at a demonstration that had been called in support of eight imprisoned hunger strikers, whose lives are in peril. They were jailed over connections to the Palestine Action group, just hours after the Metropolitan (Met) and Greater Manchester Police (GMT) said they would be “more assertive” in policing pro-Palestine protests to counter alleged anti-Semitism.
UK Safeguarding Minister Jess Phillips backed the Met’s action. “I cannot think of any interpretation other than that [it] is inciting people to violence, which has the terrible consequences,” she was cited as saying by The Times of London.
But Ben Jamal, from the Palestine Solidarity Campaign, pointed out in a statement that the Arabic word “intifada” means “shaking off or uprising against injustice”.
In the Palestinian context, the word is understood to mean civil uprising against military occupation and illegal settlement expansion, with key historical instances in 1987-93 and 2000-05, drawing brutal responses from Israel that left thousands of people dead.
Jamal criticised the lack of consultation over the new police stance, saying on X that “forces across the political establishment” were using the “grotesque racist violence on Bondi beach” to delegitimise any protest against “open genocide”.
The police crackdown follows father-and-son gunmen killing 15 people Sunday at a Hanukkah festival on the Sydney beach and an October attack on a Manchester synagogue on Yom Kippur, the holiest day of the Jewish calendar.
“Violent acts have taken place, the context has changed – words have meaning and consequence. We will act decisively and make arrests,” said the commanders of the Met and GMP in a joint statement.
Jewish groups welcomed the announcement, with the UK’s Chief Rabbi Ephraim Mirvis calling it “an important step towards challenging the hateful rhetoric we have seen on our streets, which has inspired acts of violence and terror”.
Groups like the Community Security Trust (CST), which works to provide security to protect British Jews, say anti-Semitic incidents have risen in the UK.
In the meantime, Islamophobia and attacks against Muslims in the UK, prompted by racist rhetoric in mainstream politics on the right of the political spectrum, most prevalently but not only by Nigel Farage’s Reform party and its supporters, have soared in recent years.
