Causes of Lung Cancer



What causes lung cancer?


The following website will give you a very nice summary of the possible causes of lung cancer. Basically, it is the result of cellular damage as a result of exposure to various substances that can damage the DNA of lung cells. As damage accumulates, the potential for a cell to become cancerous increases. This means that the cell(s) began growing with irregular shapes, they don`t stop growing when they should, and they have the potential to invade nearby tissues, and metastasize to other parts of the body. For a more detailed description, I recommend the NCI`s cancer site: http://www.cancer.gov/cancerinfo/types/lung
