Slow to heal or slow to diagnose cancer?

There are around 8,500 new cases of oral squamous cell carcinoma (SCC) diagnosed in the UK each year and the incidence appears to be increasing. Although surgical and non-surgical treatment options have improved significantly in the last few decades, five-year survival has not, with an average five-year survival of 56% in the UK. Providing patients have access, there are frequent opportunities for oral cancer screening by their general dental practitioner. We present two cases of SCC managed in our department, both of whom were referred following a protracted period of review in general dental practice, where the initial 'benign diagnoses' were not re-evaluated during this time. This delay can considerably impact on patient outcomes, including survival. We outline each patient's clinical course, and key learning points to help dental practitioners detect lesions that require prompt referral to the oral and maxillofacial service for urgent investigation. Key points Describes two cases of delayed referral of oral squamous cell carcinoma and their clinical progression. Outlines key learning points to help dental practitioners detect lesions requiring urgent referral. Provides the reader with an overview of oral cancer including risk factors, signs and symptoms. Emphasises why early referral is essential for improved prognosis.
