Editor's note
A meta-analysis of 25 RCTs (40,731 participants) examining whether antiobesity medications alter obesity-associated cancer risk. Tirzepatide and cagrilintide appear only within a coagonist subgroup that showed a borderline association, while overall medications showed no association. The peptide relevance is incidental to a broad drug-class question, so the subgroup signal should be read cautiously.
Plain-language abstract
This meta-analysis of 25 trials found antiobesity medications overall were not associated with reduced obesity-related cancer risk, though a coagonist subgroup including tirzepatide and cagrilintide showed a possible signal.
