    Lung cancer

    Lung cancer is cancer that starts in the lungs. The lungs are located in the chest. When you breathe, air goes through your nose, down your windpipe...

    Lung cancer - non-small cell

    The major features of the lungs include the bronchi, the bronchioles and the alveoli. The alveoli are the microscopic blood vessel-lined sacks in which oxygen and carbon dioxide gas are exchanged.

    Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. It usually grows and spreads more slowly than small cell lung cancer. There are 3...

    Lung cancer - small cell

    This chest x-ray shows adenocarcinoma of the lung. There is a rounded light spot in the right upper lung (left side of the picture) at the level of the second rib. The light spot has irregular and poorly defined borders and is not uniform in density. Diseases that may cause this type of x-ray result would be tuberculous or fungal granuloma, and malignant or benign tumors.

    Small cell lung cancer (SCLC) is a fast-growing type of lung cancer. It spreads much more quickly than non-small cell lung cancer. There are two types of...

    Lung metastases

    Bronchoscopy is a surgical technique for viewing the interior of the airways. Using sophisticated flexible fiber optic instruments, surgeons are able to explore the trachea, main stem bronchi, and some of the small bronchi. In children, this procedure may be used to remove foreign objects that have been inhaled. In adults, the procedure is most often used to take samples of (biopsy) suspicious lesions and for culturing specific areas in the lung.

    Lung metastases are cancerous tumors that start somewhere else in the body and spread to the lungs.

    Lung PET scan

    A lung positron emission tomography (PET) scan is an imaging test. It uses a radioactive substance (called a tracer) to look for disease in the lungs such as...

    Malignant mesothelioma

    Air is breathed in through the nasal passageways, travels through the trachea and bronchi to the lungs.

    Malignant mesothelioma is an uncommon cancerous tumor. It mainly affects the lining of the lung and chest cavity (pleura) or lining of the abdomen...

    Mediastinal tumor

    The major features of the lungs include the bronchi, the bronchioles and the alveoli. The alveoli are the microscopic blood vessel-lined sacks in which oxygen and carbon dioxide gas are exchanged.

    Mediastinal tumors are growths that form in the mediastinum. This is an area in the middle of the chest that separates the lungs.

    Metastatic pleural tumor

    The pleural membrane is the membrane lining the lung and the chest cavity.

    Metastatic pleural tumor is a type of cancer that has spread from another organ to the thin membrane (pleura) surrounding the lungs.

    Solitary pulmonary nodule

    This chest x-ray shows adenocarcinoma of the lung. There is a rounded light spot in the right upper lung (left side of the picture) at the level of the second rib. The light spot has irregular and poorly defined borders and is not uniform in density. Diseases that may cause this type of x-ray result would be tuberculous or fungal granuloma, and malignant or benign tumors.

    A solitary pulmonary nodule is a round or oval spot (lesion) in the lung that is seen with a chest x-ray or CT scan.

    Sputum direct fluorescent antibody (DFA)

    Sputum direct fluorescent antibody (DFA) is a test that looks for microorganisms in lung secretions.
