Lung cancer is the uncontrolled growth of abnormal cells in the lung. Normal lung tissue is made up of cells that are programmed by nature to create lungs of a certain shape and function. Sometimes the instructions to a cell go haywire these cells then start to reproduce in an uncontrolled manner without regard for the shape and function of a lung. This leads to the formation of tumors that clog up the lung and make it stop functioning as it should. Lungs are large sized organs, thereby lung cancer may grow for many years without getting detected or causing suspicion.
In fact, lung cancer can spread outside the lungs without causing any symptoms. Adding to the confusion, the most common symptom of lung cancer, a persistent cough, can often be mistaken for a cold or bronchitis. In this video, lung cancer is defined along with its incidences.
