What is lung cancer?
Lung cancer is the stage of the uncontrolled growth of abnormal cells that start off in the lungs. Usually, this cancer starts in the cells that line the air passages. These abnormal cell growth that starts growing inside the lungs divide rapidly to form tumors.
As these tumors become larger and numerous, they start affecting the lung’s ability to provide the bloodstream with oxygen. Those tumors that remain in one place of the body and do not appear to spread are called “benign tumors.”

What might be the causes of lung cancer?
Smoking cigarettes is the main cause of this cancer. Some of the studies define the relationship between smoking cigarettes and lung cancer.
The smoke of a cigarette contains more than 4,000 chemicals identified as causing cancer. If we talk about in general, a person who smokes more than one pack of cigarettes per day has a greater risk of developing this cancer than someone who has never smoked. Once a person quits smoking, the risk of this cancer gradually decreases. Pipe smoking and cigar increase the risk of lung cancer but not more than smoking cigarettes.
