Oral cancer screening: what have we learnt and what is there still to achieve?

Oral cancer is an important global healthcare problem. In the UK, the incidence is increasing and late-stage presentation is common. Determining the feasibility of a national screening program for oral cancer is therefore an important step in the prevention of the disease. Evidence exists to suggest that an oral examination of high-risk individuals may be a cost-effective screening strategy. However, questions remain over which primary care environment would be the most suitable and the criteria for a positive screen and referral. Further research is needed in the form of clinical trials or demonstration studies in primary care. The impact on secondary care, the role of auxiliaries and training needs also need to be determined. In addition, the assessment of adjunctive aids and evaluation of potential biomarkers are considered important.
