Divya Lanka, Vijay Kumar Mittapally
Lung cancer incidence has dramatically risen in the past decades. It is one of the most common malignancies worldwide and a leading cause of cancer-related deaths both among men and women. Approximately 1.5 million people worldwide die from lung cancer every year. The disease has an extremely poor prognosis and there has been no noticed improvement in the 5-year survival rate in the last 30 years. Unfortunately currently available treatments do not prevent the progressiveness of the disease. There has been lack of optimism regarding treatment advances in the last ten years, and progress in treating or predicting the risk for lung cancer has been very slow. The present review discusses about the lung cancer, its stages and causes and the preventive steps to be taken to challenge the relentless progression of the disease.
