Detailed explanation-1: -Lung cancer, also known as lung carcinoma, is a malignant lung tumor characterized by uncontrolled cell growth in the tissues of the lung. It is the leading cause of death from cancer in the United States, with more people dying from lung cancer than from colon, breast and prostate cancers combined.
Detailed explanation-2: -Transcript. Lung cancer can start in the windpipe, the main airway or the lungs. It develops when there is uncontrolled growth of abnormal cells inside one or both lungs. These cells grow to form tumours.
Detailed explanation-3: -Lung cancer develops when normal lung cells change, or mutate, in a way that alters their natural growth and death cycle, resulting in unregulated cell division that produces too many cells. The rapidly dividing cells do not carry out the functions of normal lung cells or develop into healthy lung tissue.
