Long-term use of medications for heartburn and acid reflux, known as proton pump inhibitors, does not appear to increase the risk of stomach cancer

A new study published in The BMJ by researchers at Karolinska Institutet found that long-term use of proton pump inhibitors for heartburn and acid reflux does not increase the risk of stomach cancer. The study, based on extensive Nordic health data, contradicts previous hypotheses and provides reassurance for patients needing long-term treatment.
