Cancer is an abnormality of the cell that results in uncontrolled cell growth. The abnormal cells continue dividing and form a lump or tumor. This tumor if, cancerous can invade other healthy tissues and destroy them. It is at this point known to have metastitize. Lung cancer tends to spread early after it is formed and therefore it is very dangerous and difficult to treat.
