Study shows no increase in cancer risk for most patients with reflux disease

Reflux disease manifests as acid regurgitation and heartburn and is a known risk factor for esophageal cancer. However, a new study published in The BMJ by researchers at Karolinska Institutet now reports that the majority of patients do not have a higher risk of cancer. A large-scale study from three Nordic countries shows that the cancer risk is only elevated in patients whom gastroscopy reveals to have changes in the esophageal mucosa.
