Lung Cancer

Lung cancer is a type of cancer that develops in the tissues of the lungs, most commonly in the cells that lining the airways. In both men and women, it is the leading cause of cancer death. Small cell lung cancer and non-small cell lung cancer are the two most common forms. These two types develop and are handled in distinct ways. The most frequent type of lung cancer is non-small cell lung cancer. Lung malignancies begin in the cells that line the bronchi and other sections of the lung, such as the bronchioles and alveoli. Lung carcinomas arise from epithelial cells that have been converted into malignant cells, or from tissues made up of epithelial cells. Other lung cancers, such as the rare sarcomas of the lung, are caused by the malignant transformation of mesenchymal cells' connective tissues (nerve, fat, muscle, and bone). Lung cancer can also be caused by lymphomas and melanomas (cells of the lymphoid and melanocyte lineages). The histological type of lung cancer is used to classify it. This classification is crucial for deciding disease management as well as predicting outcomes.
