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.
