The estimated four in 10 Corby adults who smoke were the target of a day of action to promote a life without cigarettes.
To tie in with national No-Smoking Day today, NHS Northamptonshire visited Asda in Corby yesterday to remind people of the help available.
Their particular focus was a free chest X-ray available to people concerned about a persistent cough, particularly the over-50s.
Any resident who is registered with a Corby GP is entitled to a free chest X-ray at the Nuffield Diagnostic Centre in Cottingham Road.
The NHS says about 39 per cent of Corby adults smoke, compared to 26 per cent in the county as a whole, and lung cancer deaths are “significantly higher” than the county average.
About 90 per cent of lung cancer cases are caused by smoking.
Kettering General Hospital consultant Dr Raja Reddy said: “We know that there is a higher prevalence of lung cancer in Corby than in other parts of the county.
“The project in Corby aims to increase awareness of the signs and symptoms of lung cancer and ideally catch people with lung cancer earlier on.
“One of the reasons for poor survival rates from lung cancer is many patients present to treatment with late stage lung cancer.
“If it is detected at an early stage, there is a higher chance of long-term survival with surgery or radical radiotherapy.”
