Lung cancer is one of the most serious diseases and one of the most common cancers in humans. In Spain, is a cancer that causes more deaths in men (and ranks third in mortality from cancer in women).

Benign and malignant tumors are named for the spot of the tumor originates. Thus, lung cancer begins to develop in the lungs.

Some malignant tumors originate elsewhere in the body and spread to the lungs. Are lung metastases. But in this case are not lung cancer itself: keep the name of their place of origin. For example, colon cancer can give lung metastases and liver metastases, but still called colon cancer.

There may be benign and malignant tumors. Benign tumors are those that do not spread to other areas and do not compromise a person’s life.

Malignant tumors often spread to other parts of the body and cause damage to body tissues and organs and can even cause death of the person.

Malignant cells can move through the lymph or blood and reach anywhere in the body causing a second tumor, called metastatic, because it is the first originated.

Lung cancer is an abnormal growth of lung cells. The disease usually occurs on the inner walls of the bronchi, and growing up can obstruct the airway and impair breathing. For this reason, generally produces shortness of breath, breathlessness and fatigue.

There are two main types of lung cancer: small cell cancer or small cell and non small cell cancer (non small or bronchogenic).
