Lung cancer screening involves examining a large group of people who do not yet have symptoms, but are at high risk of developing lung cancer. This is also referred to as population screening.
By doing so, we hope to detect lung cancer in an early stage among a particular group of people. There is a better chance of the lung cancer being treated if you have not yet encountered any symptoms. You have less chance of dying from lung cancer: early detection and treatment following lung cancer screening can prevent the death of 1 in every 4 people with lung cancer.
Nonetheless, population screening for lung cancer is still not taking place. Some important questions first need to be answered. Only then can a decision be made about whether population screening for lung cancer can be introduced.
