Doctor explains study showing GLP-1s may lower breast cancer risk
A new study suggests that GLP-1 medications may be associated with a reduced risk of developing breast cancer. The research, which analyzed records of over 111,000 women, found that those on GLP-1s had a 30% lower risk of breast cancer. While the findings are observational and not definitive, they contribute to the ongoing investigation of these medications as potential cancer prevention tools.
- ▪The study published in the JCO Oncology Practice journal examined records from the University of Pennsylvania Health System.
- ▪Women aged 45 to 80 who were overweight or obese were analyzed for breast cancer development.
- ▪GLP-1 medications are believed to reduce weight, inflammation, and improve insulin sensitivity, which may lower cancer risk.
