Lung cancer screening is the process of using tests to find the disease at an early stage, before symptoms are present. When lung cancer is detected based on symptoms, the disease is mostly at a late stage, making treatment much less effective.
Finding cancer earlier means that treatments can work better and even cure lung cancer, improving the outcomes for people living with the disease and reducing medical costs. A screening programme involves routinely checking certain groups of people at regular intervals and offering them access to smoking cessation services if they are current smokers.
