Persistent cough could be 'lung cancer sign'
A new government advertising campaign is warning the public to be vigilant about persistent coughs as they could be a sign of lung cancer.
The campaign, which is being run in TV, radio, print and online media, recommends that people with coughs lasting longer than three weeks visit their GP.
Research has shown that the public are much more aware that lumps and bleeding are warning signs of cancer than a cough.
