Washington: Frequent heartburn is positively associated with cancers of the throat and vocal cord among nonsmokers and nondrinkers, a new study has found.According to the study, the use of antacids, but not prescription medications, had a protective effect."Previous studies examining gastric reflux and cancers of the head and neck have generated mixed results," Scott M. Langevin, Ph.D., postdoctoral research fellow at Brown University in Providence, R.I, said."Most of those studies had either few numbers of cases or they were not adjusted for confounding factors. Ours is a large, population-based study with robust parameters that strongly suggests gastric reflux, which causes frequent heartburn, is an independent risk factor for cancers of the pharynx (throat) and larynx (vocal cord)," he said.
