A survey of the awareness and knowledge of oral cancer among residents in Beijing

Background The present study aimed to investigate oral cancer awareness and its related knowledge among residents in Beijing. Methods A questionnaire survey was conducted among Beijing residents concerning their knowledge of oral cancer, and its prevention and treatment. Results A total of 3055 questionnaires were completed, 45.8% by males and 54.2% by females. The ages of the respondents ranged from 15 to 93 years; 12.4% were smokers, 1.1% chewed betel nuts, and 82.5% brushed their teeth at least twice a day. Lung cancer was heard of by the most respondents, followed by gastric cancer and liver cancer; oral cancer was the least heard of. More than 60% of respondents were unaware of the risk factors and early signs of oral cancer. Conclusions This survey demonstrated a general lack of public awareness and knowledge about oral cancer. Specific measures should be taken to improve public awareness of oral cancer and its prevention and treatment.
