Abnormal cell growth in either one or both of the lungs is the simple answer to the question, What is lung cancer? In healthy individuals, the cells within the lungs go about their business duplicating at a normal rate and turning into more and more lung tissues. The lungs continue to function properly and all is well.
But in damaged lungs, this rate of cell duplication becomes uncharacteristically fast yet new lung tissue fails to develop. These damaged (cancerous) cells begin to clump together and ultimately turn into cancerous tumors. Eventually, the tumors begin to interfere with the impacted lungs ability to function normally and that is when the full impact of the disease known as lung cancer begins to be noticed.
Interestingly, although it usually takes many years for lung cancer to develop, the cells begin to take on abnormal characteristics almost immediately upon being exposed to cigarette smoke or the other environmental contaminants that can cause trouble in the lungs such as radon, asbestos, coal, air pollution, and even second-hand smoke.
