Doctor explains study showing GLP-1s may lower breast cancer risk
Summary
A new study suggests that GLP-1 medications, often used for weight loss, may reduce the risk of breast cancer by about 30% in overweight and obese women aged 45 to 80. Researchers say these drugs might lower cancer risk by reducing weight, inflammation, and improving insulin sensitivity, but more research is needed to confirm these findings.Key Facts
