<unk>  refers to the use of medical therapies, such as surgery, radiation, chemotherapy, immunotherapy, percutaneous ablation, and palliative care, alone or in combination, in an attempt to cure or lessen the adverse impact of malignant neoplasms originating in lung tissue. Lung<unk>  is an extremely heterogeneous family of malignant neoplasms, and well over 50 different histopathological variants are currently recognized under the most widely used typing system. Because these variants have differing genetic, biological, and clinical properties, including response to treatment, correct classification of lung<unk>  cases are necessary to assure that lung<unk>  patients receive optimum management. Approximately 95% of lung<unk> s are carcinoma, or tumors derived from transformed cells of epithelial lineage. Currently, nearly four dozen different histopathological variants of lung carcinoma are recognized. For clinical and treatment purposes, however, most oncologists tend to classify lung carcinomas into two major groups, namely small cell carcinoma (SCLC) and non-small cell lung<unk>  (NSCLC). This is done because of differing responses to treatment—NSCLC is comparatively less sensitive to chemotherapy and/or radiation, so surgery is the treatment of choice in these tumors. SCLC, in contrast, usually initially responds well to chemotherapy and/or radiation, but has usually metastasized widely by the time it is discovered, making surgery ineffective. In a 2010 study of patients with metastatic non–small-cell lung<unk> , "early palliative care led to significant improvements in both quality of life and mood. As compared with patients receiving standard care, patients receiving early palliative care had less aggressive care at the end of life but longer survival" which was increased by approximately three months. There are typically three objectives applied to the<unk>  and can vary by patient or individual diagnosis: (1) curing lung<unk> , (2) controlling lung<unk> , and (3) being comfortable.
