Objective: The general public’s knowledge of the risk factors for head and neck cancer is insufficient. The level of awareness of such risk factors amongst the otolaryngology clinic patient population has not yet been elucidated in the literature. Method: This individual cohort study took place at a tertiary academic center. A survey was designed and administered to all patients who presented to otolaryngology clinic from 2017 to 2018 to assess knowledge of head and neck cancer risk factors. The main outcome measures were percentage of correct responses for each cancer risk factor and comparison of percent correct between cancer and non-cancer patients. Results: A total of 510 patients were enrolled in the study including 69 patients (13.5%) with a history of head and neck cancer. The most well recognized risk factors by all patients were cigarettes (83.7%) and chewing tobacco (77.5%). Twenty-nine percent of patients correctly identified alcohol as a risk factor. Additional risk factors were poorly recognized. Cancer patients had a similar or better correct response rate than non-cancer patients except for chewing tobacco (68.1% vs 78.9% respectively). Conclusion: The general otolaryngology clinic population, especially patients with a history of head and neck cancer, demonstrated improved knowledge of some risk factors for head and neck cancer, but insufficient awareness of alcohol and HPV transmissible behaviors.
