The Help Us Help You campaign, launched on World Lung Cancer Day, targets those most at risk, including over-60s and people from working-class backgrounds who are often more reluctant to visit their GP.
The disease does not usually cause noticeable symptoms until it is spread through the lungs or into other parts of the body, meaning the outlook for the condition is not as good as many other types of cancer.
Around one in three people with the condition live for at least one year after they are diagnosed, and about one in 20 people live at least 10 years.
Cally Palmer, NHS England national cancer director said it was “imperative” that people are aware of the symptoms and come forward as quickly as possible.
Common symptoms can include having a cough for longer than three weeks, coughing up blood, or persistent breathlessness.
Professor Peter Johnson, national clinical director for cancer, added: “For lung cancer, we have not seen referrals bounce back at the same rate as other cancers.
“It is vital that people stay alert against suspected lung cancer symptoms, so if you have a continuous cough or breathlessness, don’t ignore or assume it’s something else, please visit your GP and get it checked out – it probably won’t be cancer but catching it early can help save lives.”
The NHS advises that people see their GP for a check-up if they experience any of the following warning symptoms of lung cancer.
