Frank McCaughan, MRCP(UK), MD, PhD, FRCP, University of Cambridge, Cambridge, UK, comments on the role of low dose computed tomography (CT) scans in early diagnosis of lung cancer. Data from multiple trials including the SUMMIT trial (NCT03934866) and Yorkshire Lung Screening Trial (YLST, NCT03750110) have demonstrated the efficacy of low dose CT scans in reducing lung cancer mortality. Despite the findings, low dose CT scanning has yet to be approved for nationwide usage in the UK and Dr McCaughan emphasizes the need to approve CT low dose CT scanning. This interview took place at the 20th Annual British Thoracic Oncology Group (BTOG) Conference 2022.
