Current Status of Lung Cancer Research

One of the most common cancers to cause death worldwide is lung cancer. Lung carcinoma, another name for lung cancer, is a malignant lung tumor that is characterized by unchecked cell proliferation in lung tissues. This tumor has the potential to metastasize, or expand outside of the lung, into neighboring tissue or other sections of the body, if left untreated. The majority of primary lung malignancies, also known as cancers that begin in the lung, are carcinomas that develop from epithelial cells. Small-cell lung cancer (SCLC) and non-small-cell lung carcinoma (NSCLC) are the two main primary kinds. Lung cancer is primarily caused by prolonged cigarette smoke exposure (85% of cases). Approximately 10-15% of occurrences include non-smokers. These situations are frequently brought on by a confluence of genetic predispositions and exposure to asbestos, radon gas, or other environmental pollutants such as secondhand smoke. This article provides an overview of lung cancer's epidemiology, causes, forms, symptoms, and treatments.
