The lung cancer is among the most frequent causes of death in the world. It occurs because of uncontrolled cell growth in lung tissue and if left untreated can spread to other parts of the body as well.

The smoke is the number one risk factor for getting lung cancer, but it can also develop in people who have never smoked. People who have a family history of lung cancer, especially a parent or a sibling, they are at greater risk. Other risk factors include exposure to secondhand smoke or noxious gases. Lung cancer occurs mostly in older people, almost 70% of people who have contracted over 65 years, while 3% are less than 45 years. Lung cancer is responsible for approximately 27% of all cancer deaths each year. More people die of lung cancer than in colon cancer, breast and prostate cancer combined.
