Lung Cancer Research Paper
My project is about lung cancer, which falls under the science branch of oncology. Lung cancer is the uncontrolled growth of abnormal cells in the lung. The uncontrolled reproduction of cells results in the formation of tumors that can block or compress airways and displace or damage normal lung tissue. This can make the lung stop functioning as it should. Most lung cancers start in the lining of the bronchi, or in glands below the lining of the bronchi, frequently in the periphery of the lungs. When they are exposed to irritants or carcinogens, the epithelium continually replaces itself until the cells develop chromosomal changes and become altered in size, shape, and organization. These dysplastic cells don't function well as protectors,

Small cell lung cancer, which is also called oat cell cancer, is less common than non-small cell lung cancer. This type of lung cancer usually starts in one of the larger breathing tubes, grows fairly rapidly, and is likely to be large by the time of diagnosis. Small cell lung cancer accounts for about 20 percent of all lung cancers. Non-small cell lung cancer is much more common, and usually grows and spreads more slowly than small cell lung cancer. There are 3 types of non-small cell lung cancer which are Squamous cell carcinoma, adenocarcinoma, and large cell carcinoma. Squamous cell carcinoma starts in one of the larger breathing tubes and grows relatively slowly. Adenocarcinoma starts growing near the outside surface of the lung and may vary in both size and growth rate. Some slowly growing adenocarcinomas are called bronchoalveolar cancer. Large cell carcinoma starts near the surface of the lung, grows rapidly, and is usually large when …show more content…
The condition of pleural effusion, which is the buildup of fluid between the outer lining of the lungs and the chest wall is common. This causes infection, inflammation, heart failure, or pancreatitis. A collapsed lung, known as pneumothorax, results from a buildup of air in the space between the lung and the chest wall. This prevents the lung from expanding properly when the person tries to breathe in, causing shortness of breath and chest pain. Bronchial obstruction, which is the blockage of airway, and recurrent infections, such as pneumonia, are also causes from lung
