Knowledge and perceptions of Cypriots about oral cancer

Abstract

Introduction: Oral cancer is the sixth most common cancer in the world. Cyprus recorded 312 new cases between 1998 and 2009, which represent a significant percentage of all cancers reported in Cyprus. Purpose: This study aimed to evaluate the knowledge and perceptions of group of Cypriots about oral cancer. Methods: A convenience sample of 234 people was selected from those who came to mobile clinics in 4 major cities of Cyprus and received free dental examinations. The study used a self-completion questionnaire with questions about socio-demographics, habits (smoking, alcohol consumption, visits to the dentist), plus knowledge and perceptions of oral cancer. Results: 53% (n= 124) of the respondents had heard about oral cancer, 77.4% (n= 181) knew that smoking is a risk factor for oral cancer but only 59.4% (n= 139) identified alcohol, and 38.9% (n= 91) solar irradiation as other risk factors. Although 68.4% (n= 160) responded that changing the habits of everyday life can prevent oral cancer, 38.9% (n= 91) erroneously thought that oral cancer is hereditary. In addition, only 25.6% (n= 60) mentioned that in case of a wound/lesion of their oral mucosa they would seek treatment from a dentist, while only 12% (n= 28) reported that they have been screened for oral cancer by their dentist. Those with higher education, as well as non-smokers, were more likely to have knowledge about oral cancer, while those who reported that they often visited the dentist had more chances of receiving preventive screening (p < 0.05). Conclusions: The results demonstrate a lack of adequate information in Cyprus, especially among less educated people, highlighting the need for an integrated policy planning, aiming at informing the public and health professionals about oral cancer and, at the same time, the need for introduce preventive examination within the context of the routine dental examination.
