Early stages of lung cancer are often difficult to detect on routine X-ray images, so patients miss the opportunity for early treatment. Therefore, low-dose lung CT scans are of great value in lung cancer screening, important in treatment and reducing mortality.

Despite improvements in treatment methods, patients with non-small cell lung cancer still suffer severe damage leading to recurrence and death. The 5-year survival rate is only 10-15% and this is considered a hindrance in diagnosis.
