Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, and lung cancer is one of the most common cancers. Although it is one of the most common, it is also the second most fatal cancer affecting civilization today. Lung cancer in general, occurs when a carcinogen triggers the growth of abnormal cells in the lung, the abnormal cell growth can start in the cells lining the bronchi and parts of the lung such as the bronchioles or alveoli (What Is Non-small Cell Lung Cancer?).This abnormal growth of cells will sooner or later lead to the growth of a tumor (abnormal cells growing together in clusters), which in the end will begin to produce at such a speed that the healthy cells can no longer survive, and the cancer will spread. …show more content…
The most dangerous risk factor that can lead to lung cancer is smoking. Smoking has the highest percent of lung cancer patients, making up the majority of 80-90% of lung cancer victims being smokers or prior smokers. Being around radon gas may also lead to lung cancer, but at a much lower rate than that of smokers. Even second hand smoke can cause the person to develop lung cancer, so it isn’t always smoking yourself but what can be in the air. If other cancers occur, the treatment of radiation to the chest also holds a chance of creating cancer within the lung tissue. If you or someone you know is working in a place with asbestos, soot, or tar, the risk of lung cancer is much higher. Lastly, another risk factor of developing lung cancer comes from family history. With these risk factors, it is easy to see how this cancer is the second most …show more content…
Squamous cell carcinoma is a slow growing type of lung cancer that begins in squamous cells that line the airways of the lung, squamous cell carcinoma cancer is almost always caused by smoking. The next type is large cell carcinoma, which is a type of non-small cell lung cancer that represents 10-20% of bronchogenic rapidly growing tumors. Large cell carcinoma is a fast growing and spreading cancer, because of this there is trouble treating it. The tumors found within lack any diagnostic features to suggest their diagnosis before a biopsy (minimal options of diagnosis) and are strongly connected with smoking as well (Large Cell Carcinoma). Approximately 40% of non- small cell lung cancers are adenocarcinomas; this cancer starts in the cells that secrete mucus and other substances. This type of lung cancer occurs mainly in smokers, but it is also the most common type of lung cancer seen in non-smokers, with the growth being on the slower side there is a greater probability of treatment if spotted in the early stages. With all three types of this cancer, cancer starts in the cells contained in the lung. The most probable cause of lung cancer is the inhalation of carcinogens, which includes cigarette
