Evaluation of a national lung cancer symptom awareness campaign in Wales.

Background: Lung cancer is the leading cause of cancer mortality in Wales. We conducted a before- and after- study to evaluate the impact of a four-week mass-media campaign on awareness, presentation behaviour and lung cancer outcomes.

Methods: Population-representative samples were surveyed for cough symptom recall/recognition and worry about wasting doctors' time pre-campaign (June 2016; n = 1001) and post-campaign (September 2016; n = 1013).
