An evaluation of a national mass media campaign to raise public awareness of possible lung cancer symptoms in England in 2016 and 2017.

There were small positive changes in most metrics relating to lung cancer diagnosis after this campaign. However, the pattern over time challenges whether the improvements are wholly attributable to the campaign. Given the importance of education on cancer in its own right, raising awareness of symptoms should remain important. However further research is needed to maximise the effect on health outcomes.
