Could GLP-1 Drugs Play a Role in Breast Cancer Prevention?

What if a GLP-1 medicine known for weight loss and type 2 diabetes was also linked to lower breast cancer rates? That is the question behind a new study on GLP-1 medicines. Researchers looked at health records from women who had breast imaging and found that those exposed to GLP-1 medicines had a lower rate of breast cancer than those who were not. This does not prove that GLP-1 medicines prevent breast cancer. It shows an association. But it is a strong enough signal that researchers say it deserves more study.
