The lung cancer is a disease that is growing rapidly. It is the most common cancer among men over 35 countries, mainly, in developed or industrialized countries. In the event of being diagnosed early, it can mean that the person can stay alive for more than 5 years. In contrast, only 2% surviving of those who have been diagnosed with cancer is in the worst shape.

Lung cancer is a disease resulting from abnormal cell growth in the lung tissue. This usually malignant growth may lead to metastasis, meaning, it can spread to other organs.

The main cause of lung cancer is cigarette smoking. The relationship between snuff and the occurrence of lung cancer is well established. A cigarette typically contains 4,000 harmful chemicals. It has been proven that smokers have a 20-25 times greater chance than nonsmokers.

The symptoms include cough (also coughing up blood), respiratory distress, weight loss, as well as chest pain, swelling of the neck and face and fatigue.
