GLP-1 weight-loss drugs might help protect against breast cancer, study presented at ASCO meeting suggests

A study presented at the American Society of Clinical Oncology conference suggests GLP-1 weight-loss drugs like Wegovy and Zepbound may reduce breast cancer risk by over 30% in women. The observational study analyzed health records of 111,000 women and found those prescribed GLP-1 medications had significantly lower breast cancer incidence, though researchers caution the findings do not prove causation.
