Lung Cancer Information

Cells are the smallest living units of the human body. One function is to reproduce and die when no longer useful. This process is very neat, in time and space, so there is always that allows the appropriate number of cells for each stage of life.

When this multiplication of cells occurs in an uncontrolled manner, forming lumps. These masses are called tumors.

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).
