Lung cancer, also known as lung carcinoma, is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung.[11] This growth can spread beyond the lung by the process of metastasis into nearby tissue or other parts of the body. Most cancers that start in the lung, known as primary lung cancers, are carcinomas.The two main types are small-cell lung carcinoma (SCLC) and non-small-cell lung carcinoma (NSCLC).The most common symptoms are coughing (including coughing up blood), weight loss, shortness of breath, and chest pains.
