The UK’s largest lung cancer screening trial will take place in Leeds after a £5.2m investment by Yorkshire Cancer Research.
Over 7,000 people will be screened during testing, which will be carried out in mobile vans travelling to South, East and West Leeds.
The Leeds trial is expected to start in early 2018 and will focus on smokers and ex-smokers aged 55 to 80.
Lung cancer is the biggest cancer killer in the region, with more than half the 4,500 people diagnosed every year having a very advanced form of the disease, and an extremely low chance of survival.
Yorkshire Cancer Research says it could lead to 289 cancers being diagnosed. Some 80 per cent of patients diagnosed through screening are expected to survive 10 years and the results could be used to plan a national screening programme.
