Lung cancer, a steadily growing problem, ranks as the first cause of tumor-related deaths in developed countries. The relation between lung cancer and smoking makes it a potentially avoidable disease. Found mainly in men, it has made alarming gains among women. The main prognostic factor is the possibility of receiving curative surgery; however, in real practice the diagnosis usually comes when the disease has reached an advanced stage, when only 20% can be treated surgically. Nonsurgical treatments based on chemo- and radiotherapy have not advanced appreciably in recent years, and 5-year survival is poor, estimated at only around 7% to 12% in Spain. Attempts must be made to improve preventive measures and early diagnosis in order to improve the prognosis for lung cancer patients.
