Abstract:
Chronic Obstructive Pulmonary Disease (COPD) and emphysema have been described as possible risk factors for lung cancer. We aim to assess the relationship between COPD, emphysema and the onset of lung cancer. We have developed a systematic review of the published literature in order to systematically analyze the scientific evidence available on this association, applying predefined inclusion and exclusion criteria. 11 Studies were included. Both COPD and emphysema seem to increase the risk of developing lung cancer, being this risk higher for smokers with heavier tobacco consumption. These results emphasize the need for physicians to perform spirometries in current and former smokers and lung image tests when needed in order to identify COPD and emphysema and thus select patients at higher risk of developing lung cancer.

COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
