Lung infections

Treatment of lung infections is based on the administration of antibiotics for bacterial infections (pneumonia), or antifungals for mycotic infections (aspergillosis). Under certain conditions, such as antibiotic resistance, surgery may be necessary to remove the diseased part.

Three types of lung infections are commonly treated by the Thoracic and Endocrine Surgery Division: 

Lung metastases

Primary tumors are different from secondary tumors (metastases). A primary tumor is the starting point of the cancer. Metastases are tumors that have spread to other organs from the primary tumor. Therefore, a lung metastasis is a cancer that comes from another part of the body.


Pulmonary emphysema is characterized by destruction of the lung tissue and irreversible dilation of the lungs, which lose their elasticity. It is similar to chronic obstructive pulmonary disease (COPD), one of the world's most common non-communicable diseases.

A double membrane, called the pleura, surrounds the lungs and lines the ribs. The space in between the two membranes is called the pleural cavity. Pneumothorax is when air penetrates the pleural cavity. Air that comes from a weak area in the lung (a  “hole” in the lung) causes it to collapse. This phenomenon may be local, at the top of the lung (apex), or it may extend to the entire lung.
