How serious is lung cancer?
Prognosis of Lung cancer: Survival rates have improved for non small-cell lung cancer because of advances in combination radiation/chemotherapy treatment. However, small cell lung cancer is still very difficult to treat. Small cell is the most aggressive of lung cancers, and many patients have advanced disease at the time of diagnosis. Small cell lung cancer is responsive to both chemotherapy and radiation, yet nearly all these patients eventually relapse and need additional treatment.
