A new study has identified that heartburn almost doubles the risk of developing mouth cancer.1

Researchers at Brown University in the US studied 631 patients with mouth cancer and 1,234 control subjects. They discovered that participants with frequent heartburn who were neither heavy smokers nor heavy drinkers had a 78% increased risk of developing mouth cancer. They also discovered that taking indigestion tablets had a preventive effect among those who had frequent heartburn. According to the research, those people had a 41% reduced risk of cancer of the throat and vocal cord.
