Weight Loss Injections: A Potential Cancer Prevention Strategy?
Groundbreaking research suggests that weight loss injections like Mounjaro and Ozempic, initially developed for diabetes and obesity treatment, may offer an unexpected benefit: reducing the risk of developing certain cancers. Experts propose these fat-melting injections could help protect against up to 14 types of cancer, marking a significant development in preventative medicine.
The Dual Benefit: Weight Loss and Reduced Cancer Risk
These medications, already recognized for their impact on weight management and associated health improvements such as lowering the likelihood of heart attacks, strokes, and kidney disease, are now being investigated for their potential to decrease the occurrence of weight-related cancers.
Promising Results for Colorectal Cancer
The new study indicates that these injections were most effective in reducing the risk of cancers affecting the colon and rectum. The findings are notable, given the perplexing increase in cases among individuals under 50 in recent years.
Study Highlights:
- American scientists suggest the drugs have a ‘preventative effect’ on individuals with heightened risk.
- Researchers urge caution, emphasizing the need for additional investigations to substantiate these preliminary findings.
- The study did not delve into the specific mechanisms by which GLP-1 agonists, the drug class these medications belong to, might diminish cancer risk.
Expert Insights
Lucas Mavromatis, an obesity expert at NYU Grossman School of Medicine and the lead author, commented on the importance of these findings. “Although obesity is now recognized as an increasingly important cause of cancer in the United States and worldwide, no medications have been proven to lower the cancer risk associated with obesity.” He added, “Our study begins to fill that gap by evaluating GLP-1 receptor agonists… Our results suggest they may modestly cut the chance of developing certain cancers—especially cancers of the colon and rectum—and reduce rates of death due to all causes… These data are reassuring, but more studies are required to prove causation.”
Study Methodology
The research team scrutinized data from over 170,000 obese patients with diabetes, averaging 57 years of age. Over a decade-long period, they compared cancer incidence between patients using GLP-1 agonists and those on DDP-4 inhibitors, another class of diabetes medication.
Cancers Assessed
The study evaluated the incidence of the following cancers:
- Esophageal
- Colon
- Rectum
- Stomach
- Liver
- Gallbladder
- Pancreas
- Kidney
- Post-menopausal breast
- Ovarian
- Endometrium
- Thyroid
- Multiple myeloma
- Meningiomas
Key Findings
- Patients using GLP-1s demonstrated a 7% reduction in obesity-related cancer risk compared to those on DDP-4 inhibitors.
- Accounting for other health benefits, GLP-1 users also had an 8% lower mortality rate over the 10-year observation period.
- The most significant risk reductions were observed for colon (16%) and rectal (28%) cancers.
- Obese women on GLP-1s showed an 8% lower risk of obesity-related cancers and a 20% lower risk of death from any cause, compared to those treated with DDP-4 inhibitors.
Presentation at ASCO
The complete study findings are scheduled for presentation at the American Society for Clinical Oncology (ASCO) conference in Chicago.
ASCO President’s Perspective
Dr. Robin Zon, ASCO president, noted, “This trial raises an intriguing hypothesis: that these increasingly popular GLP-1 medications… might offer some benefit in reducing the risk of developing cancer… Though this trial does not establish causation, it hints that these drugs might have a preventative effect… Future research is needed…”
Rising Popularity of Weight Loss Jabs
Originally created to treat diabetes, these weight loss jabs have gained prominence as a weight-loss aid, embraced by public figures seeking to reduce weight. An estimated half a million NHS patients and 15 million individuals in the United States are currently using these injections, which can facilitate up to a 20% bodyweight reduction within months.
Obesity and Cancer: A Clear Link
Obesity is a known risk factor for several serious health issues, including cardiovascular conditions and various forms of cancer. With approximately two-thirds of UK adults and nearly 75% of US adults classified as obese or overweight, the potential impact of these findings is substantial.
