Early Detection: Screening
From many studies it is quite clear that the prognosis for lung cancer is best if it is detected in a presymptomatic stage. It is therefore natural to conceive that the overall mortality of lung cancer could be diminished through screening of high-risk groups with chest X-rays and/or sputum cytology and/or fiber optic bronchoscopy or by other innovative methods. Through early detection more and more patients could undergo resection and the overall survival-rate improve, and since the population at risk can be clearly defined (e.g. male smokers aged over 45 years), the possibility of screening for early diagnosis and more effective treatment is highly attractive.
