“Scientists see this class of drugs, called GLP-1 agonists, as a breakthrough because of how they act on the brain to regulate the body’s hormones, slow digestion, and tamp down hunger. And in several recent studies, they show early promise in preventing many common cancers — including breast, colon, liver, and ovarian — known to be driven by obesity and excess weight…

One research letter published in JAMA Oncology last year, for example, suggests GLP-1 drugs might reduce the risk of colon cancer, even among people who are not overweight. A more recent analysis in JAMA Network Open suggests GLP-1s provide far more protection against cancer for diabetic patients than insulin treatments.

Another recent study presented at the American Society of Clinical Oncologists meeting in June, showed both bariatric surgery and GLP-1 medications dramatically reduce the risk of the 13 obesity-related cancers. Among those who had bariatric surgery, that risk declined by 22% over 10 years compared to those who received no treatment. But among those taking GLP1 medications, risk dropped by a whopping 39%.”
