Acid reflux and head and neck cancer risk: A nationwide registry over 13 years

There may be a potential association between GERD and risk of HNCs, which however merits further studies to confirm the causal relationship. Our observations indicate a need for careful extra-esophageal examination of patients with acid reflux. Our findings also underline the importance of raising awareness among clinicians regarding the possibility of concurrent HNCs in GERD patients with refractory laryngo-pharyngeal symptoms.
