This is something of a worry! You would rather expect that they would have done some significant testing before they released these drugs onto an unsuspecting public.
Although I can see their benefit (being overweight does increase cancer risk), please be careful if you are taking these drugs. Get yourself checked regularly to ensure that, if they do cause cancer for you, you can get it dealt with quickly.

⚠️ Cancer Concerns Around Popular Weight-Loss Drugs Like Ozempic
Breakthrough medications like Ozempic, Wegovy, and Mounjaro—all GLP-1 receptor agonists—have transformed weight loss and diabetes management by lowering blood sugar and suppressing appetite. Yet as their use skyrockets, scientists are investigating possible long-term cancer risks associated with these drugs.
The strongest concern centers on thyroid cancer. Animal studies show that high doses of GLP-1 drugs can trigger thyroid tumors, and a recent large French study found a possible link between prolonged human use (beyond one year) and thyroid abnormalities. As a precaution, people with a personal or family history of thyroid cancer or genetic conditions like MEN2 are advised to avoid these treatments.
Potential ties to pancreatic cancer remain speculative. While GLP-1 drugs can occasionally cause pancreatitis—an inflammation that increases pancreatic cancer risk—no clear causal link has been confirmed. Curiously, early research suggests that tirzepatide, a newer dual-acting drug, may even shrink certain tumors in animal models, though its human implications remain unknown.
It’s also important to note that obesity itself is a major cancer risk factor. Whether any reduction in cancer rates seen among users of GLP-1 drugs results from the medication’s biology or simply from weight loss remains unclear.
For now, experts stress balance: GLP-1 drugs offer powerful metabolic benefits, but long-term vigilance is essential as science continues to unravel their full safety profile.
