Patrick Maguire, MD, Oncology, answeredAccording to the National Cancer Institute's (NCI's) Surveillance, Epidemiology and End Results (SEER) Cancer Statistics Review, the five-year survival rate for lung cancer for all stages combined is a rather dismal 16%. Only about 15% of patients have localized disease when they are diagnosed. Their chance of survival at five years following a lung cancer diagnosis is 53%, relative to the general population. Those with locally advanced disease have a five-year survival of 24%. Patients who have metastatic lung cancer that's already spread to distant sites at the time of diagnosis have a 4% chance of surviving five years.
