A recent study in Israel has revealed that weight-loss drugs, particularly GLP-1 receptor agonists like liraglutide, exenatide, and dulaglutide, significantly reduce the risk of obesity-related cancers. In the study, 6,000 adults without cancer who used these medications or underwent bariatric surgery were tracked. Researchers found that the cancer risk reduction offered by these drugs was nearly on par with the effects of surgery, providing a new avenue for cancer prevention.
Surgery versus Drugs: Similar Results, Different Approaches
While bariatric surgery led to faster weight loss—approximately twice as much as the medication group—both groups saw a similar decrease in cancer risk. This surprising result suggests that weight-loss drugs may offer superior cancer protection per kilogram of weight lost, presenting a non-invasive option for those who are unable or unwilling to undergo surgery.
How GLP-1 Drugs Work: Mimicking Natural Hormones
The medications in question mimic GLP-1, a natural hormone that lowers blood sugar and promotes feelings of fullness. This process helps patients manage their appetite, leading to consistent weight loss and, as research now shows, a reduction in obesity-related cancer risks. This dual action makes these drugs a promising tool in both weight management and cancer prevention.
Findings Shared at Major Medical Conferences
The results of the study were presented at the European Congress on Obesity in Málaga and published in eClinicalMedicine, a journal from The Lancet. This exposure has brought global attention to the potential of GLP-1 drugs in cancer prevention.
Experts Praise Results, Call for More Research
Leading medical professionals are hailing the results as transformational for cancer prevention. Prof. Dror Dicker from Rabin Medical Center believes that the drugs may reduce chronic inflammation, which is a known cancer risk factor. He also suggests that newer, more powerful GLP-1 medications could offer even greater protection.
Next-Generation Injections: Mounjaro vs. Wegovy
Another study has compared the weight loss results between two popular GLP-1 drugs, Mounjaro and Wegovy. The study found that Mounjaro helped patients lose 20.2% of their body weight, while Wegovy resulted in a 13.7% weight loss. These results emphasize the growing potential of GLP-1 injections to achieve significant weight loss and, potentially, cancer risk reduction.
Weight Loss as a Key Strategy for Cancer Prevention
According to Prof. Mark Lawler from Queen’s University Belfast, the findings are a breakthrough for preventive medicine. He suggests that GLP-1 drugs could play a role in reducing the risk of several cancers, including breast, colorectal, pancreatic, and ovarian cancers. Although further biological studies are necessary, he believes that weight control could become a key factor in reducing cancer rates globally.
Potential for GLP-1 Drugs in Cancer Patients
Prof. Jason Halford from Leeds University has called for clinical trials of GLP-1 drugs in newly diagnosed cancer patients to evaluate their effects on survival outcomes. He argues that weight control after a cancer diagnosis could significantly improve the success of treatments, offering a new frontier in cancer care.
Global Push for Large-Scale Clinical Trials
A group of 54 experts from 12 countries has urged for large-scale clinical trials focused on the role of weight-loss drugs in cancer prevention. These trials could provide critical insights into how GLP-1 medications affect cancer risk in diverse populations.
UK to Launch Groundbreaking Cancer Trial
In the UK, researchers from the University of Manchester, backed by Cancer Research UK, are preparing a massive clinical trial. Expected to begin within three to five years, the trial will involve tens of thousands of participants and could provide definitive data on the potential of GLP-1 drugs in preventing cancer.
Hope for Population-Level Impact
Dr. Matthew Harris from the Manchester Cancer Research Centre believes that the potential for GLP-1 drugs to reduce cancer risk on a population level is immense. He sees the injections as a scalable solution that could bring about a significant shift in global cancer prevention strategies.
A New Era of Cancer Prevention
As research continues to unfold, it’s clear that weight-loss medications are more than just tools for slimming down—they may represent a pivotal shift in how we approach cancer prevention. The evidence is still emerging, but the implications for public health are profound. As studies advance and clinical trials expand, we may soon see these drugs as part of a global strategy to reduce cancer rates and improve long-term health outcomes.
