Why is early detection of lung cancer important ?
Lung cancer is the leading cause of cancer death. 1.8 million people die from lung cancer each year. Delay in diagnosis is the most important factor of this high death rates. Symptoms such as coughing, shortness of breath , weight loss, chest pain, bloody sputum usually appear when the disease is at an advanced stage.
Is it possible to cure lung cancer?
Only 18 0f 100 lung cancer patients survive at the end of 5 years period . This is mostly due to late diagnosis. At the time of diagnosis most of the patients have either locally advanced (stage 3) or metastatic disease (stage 4) . On the other hand if you can detect the cancer at early stages and remove it by surgery; you can have a five year survival rate of up to 90%.
What does early diagnosis mean?
Early diagnosis is to detect the disease as small as possible, before symptoms start and before it spreads to other sites of the body .
Why is early detection of lung cancer not easy?
You can detect 1-2 cm lesions on your skin easily with a careful visual inspection, or you can check your breast with your hands at your home. We can neither touch our lung tissue nor inspect it visually.

Can lung cancer be found early?
İn the recent years success of screening in improving outcomes in patients with cervical colon and breast cancers has been well documented. İn 2011 the result of a clinical study involving 53454 smokers without any complaints revealed that lung cancer screening with annual low dose ct scans . lowered the mortality and increased the early detection rates of lung cancer . In the view of this study and other studies ;lung cancer screening with low dose computed tomography is recommended for the early diagnosis of lung cancer
Screening for lung cancer with low dose ct scans is recommended in high-risk populations:
