Weight-loss drugs slash breast cancer risk by 30 in new study
A new study has found that weight-loss drugs may reduce the risk of breast cancer by up to 30%, offering a potential breakthrough in cancer prevention as obesity rates rise globally. The research, published on Thursday, suggests that medications such as GLP-1 receptor agonists—including Eli Lilly’s Mounjaro and Novo Nordisk’s Wegovy—could have secondary health benefits beyond weight management.
The study, reported by Euronews, analyzed data from women using these drugs and found a significant correlation between their use and a lower incidence of breast cancer. While the exact mechanisms remain under investigation, researchers hypothesize that the metabolic changes induced by these medications may play a role in reducing cancer risk. The findings come at a time when obesity is increasingly recognized as a major risk factor for several cancers, including breast cancer.
In Switzerland, pharmaceutical companies are ramping up awareness campaigns around obesity, a condition now linked to rising cancer rates. On March 4, digital billboards in Zurich airport displayed the message *Adipositas ist nicht Ihre Schuld* (“Obesity is not your fault”), followed by Eli Lilly’s logo—one of the leading manufacturers of obesity treatments. Similar campaigns have since appeared across Europe, from France to India, raising questions about the role of drug advertising in public health messaging. Critics argue that while these campaigns promote awareness, they also serve commercial interests, blurring the line between education and promotion .
The potential cancer-preventive effects of weight-loss drugs add urgency to ongoing debates about access and affordability. In Europe, patients and advocates have long criticized delays in making approved medications available, citing bureaucratic hurdles as a barrier to treatment. Politico Europe recently highlighted this issue, noting that while science advances rapidly, healthcare systems struggle to translate approvals into real-world access .
Meanwhile, public health officials continue to grapple with broader environmental and lifestyle factors linked to cancer. The World Health Organization (WHO) has warned that contaminated food contributes to 1.5 million deaths annually, with children particularly vulnerable. In Finland, health authorities are pushing for a ban on energy drinks for under-18s, citing concerns over addiction and malnutrition among adolescents. Spain, too, has taken action, confirming 111 cases of a rare cancer linked to textured breast implants.
As research into weight-loss drugs and cancer prevention evolves, experts stress the need for balanced regulation. While the new findings offer hope, they also underscore the complex interplay between pharmaceutical innovation, public health policy, and commercial interests. For now, the study provides a promising lead—but the path from lab to clinic remains long.

Sperm quality in Swiss recruits remains stable Contrary to the global trend, the sperm quality of young Swiss men is stable. A new study shows that key measurements of sperm quality have not fallen any further since the period 2005 to 2017. + Get the most important news from Switzerland in your inbox The study by the University of Zurich and Zurich University Hospital, published in the June issue of the specialist journal New Microbes and New Infections, compares data from 194 army recruits from 2021 with data from 2,523 young men who were examined between 2005 and 2017. The researchers found that important measurements such as semen volume, total sperm count, sperm concentration and sperm motility remained relatively constant over the years. In 2021, 41 of men had at least one sperm count below the World Health Organisation standard. In the earlier study group, the figure was 62. However, according to the researchers, this seemingly positive trend could also be explained by a bias in the selection of participants. Translated ...

Pharmas obesity campaigns juggle awareness and advertising Pharma giants are bankrolling obesity awareness campaigns globally. In an analysis, Swissinfo examines thorny questions about whether drug advertising bans are still enforceable – or even relevant. In early March, a digital billboard in the train station at Zurich airport caught my eye. It consisted of just a few words on a light green-blue screen: Adipositas ist nicht Ihre Schuld (obesity is not your fault) along with a website link, a QR code and a call to consult your doctor. A couple of seconds later, a slide in red appeared with the logo of the US firm Eli Lilly, one of the two major makers of obesity treatments. Over the next month my colleague spotted similar billboards in the French-speaking part of Switzerland, some of which were found next to ads for McDonalds. Company-sponsored posters, TV commercials and online campaigns on obesity have appeared in other countries from France to India. Its pretty unusual to see pharmaceutical company logos on advertising billboards ...

Bern parliament approves naming feminicide in crime data The parliament of the canton of Bern has voted to include feminicide as a separate category in its annual crime statistics.
