As lung cancer screening is a relatively new area, particularly to non-healthcare professionals, understanding of the procedure and risks involved are generally not well understood. Here, Mamta Ruparel, of University College London, London, UK, gives us an overview of her project, funded by the Roy Castle Lung Cancer Foundation, which investigated the impact of an information film to promote informed decision-making in individuals taking part in a lung cancer screening demonstration pilot. Dr Ruparel covers the aims, methods and promising results of the study, in addition to plans for further study. The information film can be found here: https://www.roycastle.org/lungcancerscreeningguide. This video was recorded at the British Thoracic Oncology Group (BTOG) Annual Conference 2018, held in Dublin, Ireland.
